DESCRIPTION
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 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.
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.
