AMS1117 3.3V SOT223 Regulator IC

AMS1117 3.3V SOT223 Regulator IC is a series of low dropout three -terminal regulators with a dropout of 3.3V at 1A load current. It features a very low standby current 2mA compared to 5mA of a competitor. Other than a fixed version, Vout = 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, 5V, and 12V, AMS1117 has an adjustable version, which can provide an output voltage from 1.25 to 12V with only two external resistors.

The Regulator IC offers thermal shut down and current limit functions, to assure the stability of chip and power system. And it uses a trimming technique to guarantee output voltage accuracy within 2%. Other output voltage accuracy can be customized on demand, such as 1%.
