General Description
SSP1117 is a series of low dropout three-terminal
regulators with a dropout of 1.3V at 1A load current.
SSP1117 features a very low standby current 2mA
compared to 5mA of competitor.
2.85V, 3.3V and 5V, SSP1117 has an adjustable version,
which can provide an output voltage from 1.25 to 12V with
only two external resistors.
SSP1117 offers thermal shut down function, to assure the
Other than a fixed version, Vout=1.2V, 1.5V, 1.8V, 2.5V,
