Description
BCT1117B is a series of low dropout
three-terminal regulators with a dropout of 1.3V
at 0.8A load current. BCT1117B 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, BCT1117B has an
adjustable version, which can provide an output
voltage from 1.25 to 12V with only two external
resistors.
BCT1117B 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%.
BCT1117B is available in SOT-223, TO-252
power package.
