DESCRIPTION

The REG1117 is a family of three-terminal volt-

age regulators capable of up to 800mA output.

Fixed output models include 2.85V, 3V, 3.3V

and 5V versions. The REG1117A provides 1A

of output current in an adjustable version. 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.

T_J= 25°C

Output Current (mA)

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.

REG1117 and REG1117A are packaged in an

SOT-223 surface-mount package, suitable for

reflow soldering techniques.
