SC1592

Low Dropout High Performance

Adjustable Positive Voltage Regulator

POWER MANAGEMENT

Description

Features

The SC1592 is a 3A low dropout high performance Wide input range, V_IN= 1.25V to 16V,

linear voltage regulator, that provides a low voltage, high

current output with a minimum of external components,

utilizing dual supply configuration.

V_CNTL= 3V to 16V

3A Guaranteed Output Current

260mV (typ) @ 3A dropout voltage in dual supply

mode

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.

1% Initial Accuracy

Adjustable output voltage, down to 0.8V

Programmable current limiting and thermal

shutdown

Fast transient response

Excellent line and load regulation

Power SO-8 and 7-lead DDPAK

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.

Applications

The SC1592 voltage regulator is available in 7-lead DDPAK

and SOIC-8L EDP packages.

Low voltage logic supplies

Microprocessor and chipset supplies
