Texas Instruments LP3961ESX-2.5

Description
The LP3961/LP3964 series of fast ultra low-dropout linear regulators operate from a 2.5V to 7.0V input supply. A wide range of preset output voltage options are available. These ultra low dropout linear regulators respond very fast to step changes in load, making them suitable for low voltage microprocessor applications. The LP3961/LP3964 are developed on a CMOS process, which allows low quiescent current operation independent of output load current. This CMOS process also allows the LP3961/LP3964 to operate under extremely low dropout conditions.
