LP2956A Datasheet | National Semiconductor

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 m V at 1 m A load current and 470 m V at 250 m A 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 m A), and additional 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 auxiliary parator is included, whose inverting input is tied to the 1.23V reference. Reverse battery protection is...
