Overview

The MIC5319-3.3YD5-TR is a high-performance, 500mA LDO regulator designed for noise-sensitive portable applications. It provides a fixed 3.3V output with high Power Supply Rejection Ratio (PSRR) and ultra-low dropout voltage, making it suitable for maintaining regulation in battery-powered systems.

Why Choose This Part

This regulator offers a high 500mA output current in a small TSOT-23-5 footprint, whereas many LDOs in this size are limited to 150mA or 300mA. It features internal protection for over-current and over-temperature conditions and is stable with low-ESR ceramic capacitors.

Applications

Audio Codec Power
High PSRR of 70dB at 1kHz ensures clean power rails for high-fidelity audio signals.
RF and Wireless Handsets
Low-noise performance and high current capability support power-hungry wireless transceivers.
Fiber Optic Modules
Provides stable 3.3V regulation within compact TSOT-23-5 packaging for optical networking components.
Portable PC Peripherals
Logic-controlled enable pin and low shutdown current of 0.5uA help extend battery life in mobile computing.

Getting Started

To implement this LDO, place a 1uF ceramic capacitor on the output and input pins close to the device. Use the EN pin to control the power state; pull it high to enable the regulator or low to enter a 0.5uA shutdown mode.
