L4993 Datasheet Low Drop Voltage Regulator

Manufacturer: STMicroelectronics

Overview: L4993 Low drop voltage regulator.

General Description

The L4993 is a monolithic integrated 5V Voltage regulator with a low drop voltage at currents up to 150mA.The output voltage regulating element consists in a p-channel MOS and the regulation is performed regardless of input voltage transients up to 40V.

The high precision of the output voltage is obtained with a pre-trimmed reference voltage.

The L4993 is protected against short circuit and an over-temperature protection switches off the device in case of extremely high power dissipation.

Key Features
