TO-92 (Top View)

This series of fixed-voltage monolithic integrated-cir-cuit voltage regulators is designed for a wide range of applications. These applications include on-card regulation for elimination of noise and distribution problems associated with single-point regulation. In addition, they can be used with power-pass elements to make high-current voltage regulators. Each of these regulators can deliver up to 100mA of output current. The internal limiting and ternal shutdown fea-tures of these regulators make them essentially im-mune to overload. When used as a replacement for a Zener diode-resistor combination, an effective im-provement in output impedance can be obtained to-gether with lower-bias current.

The input voltage must remain typically 2V above the output voltage even during the low point on the input ripple voltage.Note2 : Cin is required if regulator is located an appreciable distance from power supply filter.Note3 : C OUT is not needed for stability; however, it does improve transient response.

The APL78L05/12 Series of fixed voltage regulators are designed with Thermal Overload Protection that shuts down the circuit when subjected to an exces-sive power overload condition. Internal Short Circuit Protection limits the maximum current the circuit will pass.

In many low current applications, compensation ca-pacitors are not required. However, it is recom-mended that the regulator input be bypassed with a capacitor if the regulator is connected to the power supply filter with long wire lengths, or if the output load capacitance is large. The input bypass capaci-tor should be selected to provide good high-frequency characteristics to insure stable operation under all load conditions. A 0.33μF or larger tantalum, mylar,or other capacitor having low internal impedance at high frequencies should be chosen. The bypass ca-pacitor should be mounted with the shortest possible leads directly across the regulators input terminals.Good construction techniques should be used to mini-mize ground loops and lead resistance drops since the regulator has no external sense lead. Bypassing the output is also recommended.

The APL78L00 regulators can also be used as a cur-rent source when connected as above. In order to minimize dissipation the APL78L05 is chosen in this application. Resistor R determines the current as follows :

I O = + I B

5.0V R

I B =3.8mA over line and load changes

For example, a 100mA current source would require R to be a 50?, 1/2W resistor and the output voltage compliance would be the input voltage less 7V.Figure 2. ±15V Tracking Voltage Regulator
