800mA and 1A Low Dropout Positive Regulator

1.8V, 2.5V, 2.85V, 3.3V, 5V, and Adjustable

FEATURES

● FIXED AND ADJUSTABLE VERSIONS

DESCRIPTION

The REG1117 is a family of easy-to-use three-termi-

nal voltage regulators. The family includes a variety of

fixed- and adjustable-voltage versions, two currents

(800mA and 1A) and two package types (SOT-223

and DDPAK). See the chart below for available op-

tions.

● 2.85V MODEL FOR SCSI-2 ACTIVE

TERMINATION

● OUTPUT CURRENT:

REG1117: 800mA max

REG1117A: 1A max

Output voltage of the adjustable versions is set with

two external resistors. The REG1117’s low dropout

voltage allows its use with as little as 1V input-output

voltage differential.

● OUTPUT TOLERANCE: ±1% max

● DROPOUT VOLTAGE:

REG1117: 1.2V max at I_O= 800mA

REG1117A: 1.3V max at I_O= 1A

Laser trimming assures excellent output voltage accu-

racy without adjustment. An NPN output stage allows

output stage drive to contribute to the load current for

maximum efficiency.

● INTERNAL CURRENT LIMIT

● THERMAL OVERLOAD PROTECTION
