General Description
The G1085 is a low dropout linear regulator with a
dropout of 1.2V at 3A 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 G1085 provides over temperature and over
current protection circuits to prevent it from being
damaged by abnormal operating conditions.
The G1085 is available in TO-252 package and
TO- 263 packages. A minimum of 100µF tantalum
electrolytic capacitor is required at the output to
improve the transient response and stability.
