LM1117/LM1117I

800mA Low-Dropout Linear Regulator

General Description

The LM1117is a series of low dropout voltage regulators with a dropout of1.2V at800mA of load current.It has the same pin-out as National Semiconductor’s industry standard LM317.

The LM1117is available in an adjustable version,which can set the output voltage from1.25V to13.8V with only two external resistors.In addition,it is also available in five fixed voltages,1.8V,2.5V,2.85V,3.3V,and5V.

The LM1117offers current limiting and thermal shutdown.Its circuit includes a zener trimmed bandgap reference to as-sure output voltage accuracy to within±1%.

The LM1117series is available in LLP,TO-263,SOT-223, TO-220,and TO-252D-PAK packages.A minimum of10μF tantalum capacitor is required at the output to improve the transient response and stability.Features

Application Note

1.0EXTERNAL CAPACITORS/STABILITY

1.1Input Bypass Capacitor

An input capacitor is recommended.A10μF tantalum on the input is a suitable input bypassing for almost all applications.

1.2Adjust Terminal Bypass Capacitor

The adjust terminal can be bypassed to ground with a by-pass capacitor(C ADJ)to improve ripple rejection.This by-pass capacitor prevents ripple from being amplified as the output voltage is increased.At any ripple frequency,the impedance of the C ADJ should be less than R1to prevent the ripple from being amplified:

1/(2π*f RIPPLE*C ADJ)

The R1is the resistor between the output and the adjust pin. Its value is normally in the range of100-200?.For example, with R1=124?and f RIPPLE=120Hz,the C ADJ should be> 11μF.

1.3Output Capacitor

The output capacitor is critical in maintaining regulator sta-bility,and must meet the required conditions for both mini-mum amount of capacitance and ESR(Equivalent Series Resistance).The minimum output capacitance required by the LM1117is10μF,if a tantalum capacitor is used.Any increase of the output capacitance will merely improve the loop stability and transient response.The ESR of the output capacitor should range between0.3?-22?.In the case of the adjustable regulator,when the C ADJ is used,a larger output capacitance(22μf tantalum)is required.

2.0OUTPUT VOLTAGE

The LM1117adjustable version develops a1.25V reference voltage,V REF,between the output and the adjust terminal. As shown in Figure1,this voltage is applied across resistor R1to generate a constant current I1.The current I ADJ from the adjust terminal could introduce error to the output.But since it is very small(60μA)compared with the I1and very constant with line and load changes,the error can be ig-

nored.The constant current I1then flows through the output

set resistor R2and sets the output voltage to the desired

level.

For fixed voltage devices,R1and R2are integrated inside

the devices.

3.0LOAD REGULATION

The LM1117regulates the voltage that appears between its

output and ground pins,or between its output and adjust

pins.In some cases,line resistances can introduce errors to

the voltage across the load.To obtain the best load regula-

tion,a few precautions are needed.

Figure2,shows a typical application using a fixed output

regulator.The Rt1and Rt2are the line resistances.It is

obvious that the V LOAD is less than the V OUT by the sum of

the voltage drops along the line resistances.In this case,the

load regulation seen at the R LOAD would be degraded from

the data sheet specification.To improve this,the load should

be tied directly to the output terminal on the positive side and

directly tied to the ground terminal on the negative side.

m Application Note

(Continued)

When the adjustable regulator is used (Figure 3),the best performance is obtained with the positive side of the resistor R1tied directly to the output terminal of the regulator rather than near the load.This eliminates line drops from appearing effectively in series with the reference and degrading regu-lation.For example,a 5V regulator with 0.05?resistance between the regulator and load will have a load regulation due to line resistance of 0.05?x I L .If R1(=125?)is con-nected near the load,the effective line resistance will be 0.05?(1+R2/R1)or in this case,it is 4times worse.In addition,the ground side of the resistor R2can be returned near the ground of the load to provide remote ground sens-ing and improve load regulation.

4.0PROTECTION DIODES

Under normal operation,the LM1117regulators do not need any protection diode.With the adjustable device,the internal resistance between the adjust and output terminals limits the current.No diode is needed to divert the current around the regulator even with capacitor on the adjust terminal.The adjust pin can take a transient signal of ±25V with respect to the output voltage without damaging the device.

When a output capacitor is connected to a regulator and the input is shorted to ground,the output capacitor will discharge into the output of the regulator.The discharge current de-pends on the value of the capacitor,the output voltage of the regulator,and rate of decrease of V IN .In the LM1117regu-lators,the internal diode between the output and input pins

can withstand microsecond surge currents of 10A to 20A.With an extremely large output capacitor (≥1000μF),and with input instantaneously shorted to ground,the regulator could be damaged.

In this case,an external diode is recommended between the output and input pins to protect the regulator,as shown in Figure 4.

5.0HEATSINK REQUIREMENTS

When an integrated circuit operates with an appreciable current,its junction temperature is elevated.It is important to quantify its thermal limits in order to achieve acceptable performance and reliability.This limit is determined by sum-ming the individual parts consisting of a series of tempera-ture rises from the semiconductor junction to the operating environment.A one-dimensional steady-state model of con-duction heat transfer is demonstrated in Figure 5.The heat generated at the device junction flows through the die to the die attach pad,through the lead frame to the surrounding case material,to the printed circuit board,and eventually to the ambient environment.Below is a list of variables that may affect the thermal resistance and in turn the need for a heatsink.

m Application Note

(Continued)

The LM1117regulators have internal thermal shutdown to protect the device from over-heating.Under all possible operating conditions,the junction temperature of the LM1117must be within the range of 0?C to 125?C.A heatsink may be required depending on the maximum power dissipation and maximum ambient temperature of the application.To deter-mine if a heatsink is needed,the power dissipated by the regulator,P D ,must be calculated:I IN =I L +I G

P D =(V IN -V OUT )I L +V IN I G

Figure 6shows the voltages and currents which are present in the circuit.

The next parameter which must be calculated is the maxi-mum allowable temperature rise,T R (max):

T R (max)=T J (max)-T A (max)

where T J (max)is the maximum allowable junction tempera-ture (125?C),and T A (max)is the maximum ambient tem-perature which will be encountered in the application.

Using the calculated values for T R (max)and P D ,the maxi-mum allowable value for the junction-to-ambient thermal resistance (θJA )can be calculated:θJA =T R (max)/P D If the maximum allowable value for θJA is found to be ≥136?C/W for SOT-223package or ≥79?C/W for TO-220package or ≥92?C/W for TO-252package,no heatsink is needed since the package alone will dissipate enough heat to satisfy these requirements.If the calculated value for θJA falls below these limits,a heatsink is required.

As a design aid,Table 1shows the value of the θJA of SOT-223and TO-252for different heatsink area.The copper patterns that we used to measure these θJA s are shown at the end of the Application Notes Section.Figure 7and Figure 8reflects the same test results as what are in the Table 1Figure 9and Figure 10shows the maximum allowable power dissipation vs.ambient temperature for the SOT-223and TO-252device.Figures Figure 11and Figure 12shows the maximum allowable power dissipation vs.copper area (in 2)for the SOT-223and TO-252devices.Please see AN1028for power enhancement techniques to be used with SOT-223and TO-252packages.
