REG102-33 DMOS 250mA 低压降 (LDO) 稳压器

REG102-33 描述

The REG102 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 150mV 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 and require expensive low ESR capacitors greater than 1µF. Typical ground pin current is only 600µA (at IOUT = 250mA) and drops to 10nA when not enabled. Unlike regulators with PNP pass devices, quiescent current remains relatively constant over load variations and under dropout conditions. The REG102 has very low output noise (typically 28µVrms for VOUT = 3
