LP2956 Datasheet (National Semiconductor) - Dual Micropower Low-Dropout Voltage Regulators

LP2956, Dual Micropower Low-Dropout Voltage Regulators

The LP2956 is a micropower voltage regulator with very low quiescent current (170 µA typical at light loads) and very low dropout voltage (typically 60 mV at 1 mA load current and 470 mV at 250 mA load current on the main output).

The LP2956 retains all the desirable characteristics of the LP2951, b

LP2956 Features

* The auxiliary output is always on (regardless of main output status), so it can be used to power memory circuits. Quiescent current increases only slightly at dropout, which prolongs battery life. The error flag goes low if the main output voltage drops out of regulation. An open-collector auxiliar
