Texas Instruments LP3965ET-ADJ

Description
The LP3962/LP3965 series of fast ultra low-dropout linear regulators operate from a 2.5V to 7.0V input supply. Wide range of preset output voltage options are available. These ultra low dropout linear regulators respond very fast to step changes in load, which makes them suitable for low voltage microprocessor applications. The LP3962/LP3965 are developed on a CMOS process which allows low quiescent current operation independent of output load current. This CMOS process also allows the LP3962/LP3965 to operate under extremely low dropout conditions.

Features
Ultra low dropout voltage; typically 38mV at 150mA load current and 380mV at 1.5A load current
Low ground pin current: Typically 5mA at 1.5A load current
Typically 15μA quiescent current when the shutdown pin is pulled low
Error flag goes low when the output voltage drops 10% below nominal value (for LP3962)
Sense pin improves regulation at remote loads (For LP3965)
Multiple output voltage options are available ranging from 1.2V to 5.0V and adjustable (LP3965), with a specified accuracy of ±1.5% at room temperature, and ±3.0% over all conditions (varying line, load, and temperature)
