BL1117

1A Low Dropout Voltage Regulator

Outline：

Features：

Other than a fixed version and an

adjustable version, output value can be

customized on command.

•

BL1117 is a series of low dropout three-

terminal regulators with a dropout of 1.2V at

1A load current.

•

Maximum output current is 1A

Other than a fixed version（Vout＝

1.8V,2.5V,2.85V,3.3V,5V）, BL1117 has an

adjustable version, which can provide an

output voltage from 1.25 to 13.8V with only

two external resistors。

Output voltage accuracy is within ±1％

Range of operation input voltage: Max

15V

•

Line regulation: 0.2％

Load regulation: 0.4％

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 ±1％.

Environment Temperature: -40℃~85℃

Applications：

•

Power Management for Computer
