三、General Description

 FS1117 is a series of low dropout three-terminal regulators 

with a dropout of 1.3V at 1A load current.  FS1117features 

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, 

2.85V，3.3V, and 5V,  FS1117 has an adjustable version, 

which can provide an output voltage from 1.25 to 12V with 

only two external resistors.

 FS1117 offers thermal shut down function, 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%.

 FS1117 is available in SOT-223, TO-252 power package
