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.
