LP2956/LP2956A Dual Micropower Low-Dropout Voltage
Regulators
General Description
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, but offers increased output current (main output), an auxiliary LDO adjustable regulated output (75 mA), and additional features.
The auxiliary output is always on (regardless of main output status), so it can be used to power memory circuits.
