Description

General part information

LP2952-N Series

The LP2952 and LP2953 are micropower voltage regulators with very low quiescent current (130 µA typical at 1-mA load) and very low dropout voltage (typically 60 mV at light load and 470 mV at 250-mA load current). They are ideally suited for battery-powered systems. Furthermore, the quiescent current increases only slightly at dropout, which prolongs battery life.

The LP2952 and LP2953 retain all the desirable characteristics of the LP2951, but offer increased output current, additional features, and an improved shutdown function.

The automatic output discharge pulls the output down quickly when the shutdown is activated.
