LF90AB Datasheet Very Low Drop Voltage Regulators

Manufacturer: STMicroelectronics

Overview: LF00 series Very low drop voltage regulators with inhibit.

General Description

The LF00 series are very Low Drop regulators available in PENTAWATT, TO-220, TO-220FP, DPAK and PPAK package and in a wide range of output voltages.

The very Low Drop voltage (0.45V) and the very low quiescent current make them particularly Schematic diagram TO-220 TO-220FP PPAK DPAK PENTAWATT suitable for Low Noise, Low Power applications and specially in battery powered systems.

In the 5 pins configuration (PENTAWATT and PPAK) a Shu
