L1119 CMOS IC

1.5A LOW DROPOUT REGULATORS

DESCRIPTION

The UTC L1119 is a fast ultra low-dropout linear regulator that developed in CMOS process which allows low quiescent current operation independent of output load current. This CMOS process also allows the device to operate under extremely low dropout conditions.

The UTC L1119 allows to operate from a 2.5V~7.0V input supply. Wide range of preset output voltage options are available and respond very fast to step changes in load which makes them suitable for low voltage microprocessor applications.

FEATURES

* Low ground current

* Load regulation of 0.04%

* Output current of 1.5A DC is guaranteed * Accurate output voltage.(± 1.5%)

* Extremely low output capacitor requirements * Over temperature/ Over current protection

*Pb-free plating product number: L1119L-xx

Shutdown Threshold T SHDN165 °C Thermal Shutdown Hysteresis T HYS 10 °C Note: Dropout voltage is defined as the minimum input to output differential voltage at which the output drops 2% below the nominal value. Dropout voltage specification applies only to output voltages of 2.5V and above. For output voltages below 2.5V, the drop-out voltage is nothing but the input to output differential, since the minimum input voltage is 2.5V.
