TX1117 is a series of low dropout three-terminal regulators
with a dropout of 1 3V at 1A load current. TX1117 features
a very low standby current 2mA compared to 5mA of
Other than a fixed version, Vout= 1.2V, 1.5V, 1.8V, 2.5V,
2.85V，3.3V, and 5V, TX1117 has an adjustable version,
which can provide an output voltage from 1.25 to 12V with
only two external resistors.
TX1117 offers thermal shut down function, to assure the
stability of chip and power system. And it uses trimming
technique to guarantee output voltage accuracy within
2%. Other output voltage accuracy can be customized on
demand, such as 1%.
TX1117 is available in SOT-223, TO-252 power package.
