General Description
The G1084-XX is a low dropout linear regulator
with a dropout of 1.3V at 5A of load current. It is
available in three fixed voltages: 1.5V, 1.8V, 2.5V
and 3.3V. Refer to the G1084 for the adjustable
version.
The G1084-XX provides over temperature and
over current protection circuits to prevent it from
being damaged by abnormal operating conditions.
The G1084-XX is available in TO-252 and TO-263
packages. A minimum of 220F tantalum electro-
lytic capacitor is required at the output to improve
the transient response and stability.
