REG1117FA-25/500G3 DESCRIPTION
The REG1117 is a family of easy-to-use three-terminal voltage regulators. The family includes a variety of fixedand 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’s low dropout voltage allows its use with as little as 1V input-output voltage differential.
