BCT1117 is a series of low dropout
three-terminal regulators with a dropout of 1.3V
at 1A load current. BCT1117 features a very low
standby current 2mA compared to 5mA of
Other than a fixed version, Vout = 1.2V, 1.8V,
2.5V, 3.3V, 5V, and 12V, BCT1117 has an
adjustable version, which can provide an output
voltage from 1.25 to 12V with only two external
BCT1117 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%.
BCT1117 is available in SOT-223, TO-252
