BL1117C Datasheet, PDF (1/9 Pages) SHANGHAI BELLING CO., LTD. – 1A Bipolar Linear Regulator

BL1117C
DESCRIPTION
BL1117C is a series of low dropout three-terminal
regulators with a dropout of 1.3V at 1A load current.
BL1117C 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, BL1117C has an adjustable
version, which can provide an output voltage from
1.25 to 12V with only two external resistors.
BL1117C 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%
BL1117C is available in SOT-223, TO-252 power
package.
