SC1592

Low Dropout High Performance

Adjustable Positive Voltage Regulator

Revision: January 27, 2004

Description

Features

Applications

Typical Application Circuit

The SC1592 is a 3A low dropout high performance

linear voltage regulator, that provides a low voltage, high

current output with a minimum of external components,

utilizing dual supply configuration.

The SC1592 offers a wide input voltage range from 1.25V

to 16V and is ideal for applications that need to convert

down to 0.8V.

Additionally, the SC1592 is fully protected with an exter-

nally programmable current limit, and thermal shutdown.

Also, there is an EN input which enables or shuts down

the device.

The SC1592 voltage regulator is available in 7-lead DDPAK

and SOIC-8L EDP packages.
