Overview
BL1117 DESCRIPTION BL1117 is a series of low dropout three-terminal regulators with a dropout of 1.
3V at 1A load current.
BL1117 features a very low standby current 2mA compared to 5mA of competitor.
Other than a fixed version, Vout = 1.
2V, 1.
5V, 1.
8V, 2.
5V, 3.
3V, 5V, and 12V, BL1117 has an adjustable version, which can provide an output voltage from 1.
25 to 12V with only two external resistors.
BL1117 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% BL1117 is available in SOT-223, TO-252 power package.
