G1084-XX
5A Low-Dropout Linear Regulator
Features
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.
Available in 1.5V, 1.8V, 2.5V, 3.3V version
TO-252,TO-263 and TO-263T package
Internal short circuit current limiting
Internal over temperature protection
Output current 5A
The G1084-XX provides over temperature and
over current protection circuits to prevent it from
being damaged by abnormal operating conditions.
Applications
Post regulation for switching DC/DC con-
verter
The G1084-XX is available in TO-252, TO-263 and
TO-263T packages. A minimum of 220µF tanta-
lum electrolytic capacitor is required at the output
to improve the transient response and stability.
