SBVS001B – OCTOBER 2001

800mA and 1A Low Dropout Positive Regulator

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

DESCRIPTION

FEATURES

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

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 options.

ꢀ FIXED AND ADJUSTABLE VERSIONS

ꢀ 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 accuracy

without adjustment. An NPN output stage allows output

stage drive to contribute to the load current for maximum

efficiency.
