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.
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.
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.
