BL1117

1A Bipolar Linear Regulator

DESCRIPTION

FEATURES



Other than a fixed version and an adjustable

version, output value can be customized on

demand.

Maximum output current is 1A

Range of operation input voltage: Max 12V

Standby current: 2mA (typ.)

Line regulation: 0.1%/V (typ.)

Load regulation: 10mV (typ.)

Environment Temperature: -40C~85C

BL1117 is a series of low dropout three-terminal

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

BL1117 features 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, 3.3V, 5V, and 12V, BL1117 has an adjustable

version, which can provide an output voltage from

1.25 to 12V with only two external resistors.

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 2%.

Other output voltage accuracy can be customized

on demand, such as 1%

APPLICATIONS
