TX1117 GENERAL DESCRIPTION:
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 competitor.
Other than a fixed version, Vout = 1.2V, 1.8V, 2.5V, 3.3V, 5V, and 12V, 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 and current limit functions, 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.
