LF25AB Datasheet Very Low Drop Voltage Regulator

Manufacturer: STMicroelectronics

Overview: LFXX Very low drop voltage regulator with inhibit function Datasheet - production.

General Description

The LFXX is a very low drop regulator available in TO-220, TO-220FP, DPAK and PPAK packages and in a wide range of output voltages.

The low drop voltage (0.45 V) and low quiescent current make it particularly suitable for low-noise, low-power applications and especially in batterypowered systems.
