General Description
The G1117 is a low dropout linear regulator with a
dropout of 1.2V at 800mA of load current and 1.3V at
1A of load current. It is available in an adjustable
version, which can set the output from 1.25V to 5V
with only two external resistors.
The G1117 provides over temperature and over cur-
rent protection circuits to prevent it from being dam-
aged by abnormal operating conditions.
The G1117 is available in TO-252, SOT-223 and
TO-92 packages. A minimum of 10μF tantalum elec-
trolytic capacitor is required at the output to improve
the transient response and stability.
