REG113NA-5/3KG4 Description
The REG113NA-5/3KG4 is a low-noise, low-dropout linear regulator with a low ground pin current. Its new DMOS topology provides a significant improvement over previous designs, including low-dropout voltage (only 250mV typ at full load), and better transient performance. In addition, no output capacitor is required for stability, unlike conventional low-dropout regulators that are difficult to compensate for and require expensive low ESR capacitors greater than 1μF.
