REG103 - 500mA Low-Dropout Regulator

General Description

The REG103 is a family of low-noise, low-dropout, linear regulators with low ground pin current.

Its new DMOS topology provides significant improvement over previous designs, including low-dropout voltage (only 115mV typ at full load), and better transient performance.
