REG1117

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). 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.
