General Description
The G1085-XX is a low dropout linear regulator
with a dropout of 0.8V at 3A of load current. It is
available in three fixed voltages: 1.5V, 1.8V, 2.5V
and 3.3V. Refer to the G1085 for the adjustable
version.
The G1085-XX provides over temperature and
over current protection circuits to prevent it from
being damaged by abnormal operating conditions.
The G1085-XX is available in TO-220 and TO-263
packages. A minimum of 220µF tantalum electro-
lytic capacitor is required at the output to improve
the transient response and stability.
