General Description

The G1084 is a low dropout linear regulator with a

dropout of 1.2V at 5A of load current. It is avail-

able in an adjustable version, which can set the

output from 1.25V to 5V with only two external

resistors.

The G1084 provides over temperature and over

current protection circuits to prevent it from being

damaged by abnormal operating conditions.

The G1084 is available in TO-220, TO-252, TO-263

and TO-263T packages. A minimum of 220µF

tantalum electrolytic capacitor is required at the

output to improve the transient response and sta-

bility.
