Description

Maturity status link

The ST732 is 300 mA LDO regulator, designed to be used in several medium voltage

applications.

ST732

Ultra-low quiescent current of 5 µA makes it suitable for applications permanently

connected to power supply/battery.

This feature is also useful when electronic modules remain permanently turned on.

The ST732 embeds protection functions, such as: current limit, short-circuit and

thermal shutdown. The extended input voltage range, very low drop voltage and

low quiescent current features make it suitable also for low power after-market

automotive and consumer applications.
