LP2953QML - Adjustable Micropower Low-Dropout Voltage Regulators

Description

The LP2953A is a micropower voltage regulator with very low quiescent current (130 μA typical at 1 mA load) and very low dropout voltage (typ.

60 mV at light load and 470 mV at 250 mA load current).

It is ideally suited for battery-powered systems.
