General Description
The G1117-XX is a low dropout linear regulator
with a dropout of 1.3V at 1A of load current. It is
available in four fixed voltage: 1.5V, 1.8V, 2.5V,
3.3 and 3.5V versions.
The G1117-XX provides over temperature and
over current protection circuits to prevent it from
being damaged by abnormal operating conditions.
The G1117-XX is available in SOT-223 packages.
A minimum of 10
µ
F tantalum electrolytic capacitor
is required at the output to improve the transient
response and stability.
