Overview

The MD57XX series is a low-noise LDO that can supply up to 300 mA output current. Designed to meet the requirements of RF and analog circuits, the MD57XX series device provides low noise, high PSRR, low quiescent current, and low line or load transient response figures. Using new innovative design techniques, the MD57XX series offers ultra-low noise performance without a noise bypass capacitor and the ability for remote output capacitor placement. Using new innovative design techniques, the MD57XX series offers ultra-low noise performance without the need for a separate noise filter capacitor. The MD57XX series is designed to perform with a single 1 μF input capacitor and a single 1 μF ceramic output capacitor. With a reasonable PCB layout, the single 1 μF ceramic output capacitor can be placed up to 10 cm away from the MD57XX series device.
