REG1117A

SBVS001D − OCTOBER 1992 − REVISED JULY 2004

800mA and 1A Low Dropout Positive Regulator

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

FEATURES

DESCRIPTION

FIXED AND ADJUSTABLE VERSIONS

2.85V MODEL FOR SCSI-2 ACTIVE

TERMINATION

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.

OUTPUT CURRENT:

REG1117: 800mA max

Output voltage of the adjustable versions is set with two

external resistors. The REG1117 low dropout voltage

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

differential.

REG1117A: 1A max

OUTPUT TOLERANCE: + 1% max

DROPOUT VOLTAGE:

REG1117: 1.2V max at I = 800mA

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.

REG1117A: 1.3V max at I = 1A
