Overview

The MIC29150-3.3WT is a high-current, high-accuracy LDO voltage regulator capable of delivering up to 1.5A of output current. It features a low dropout voltage of 0.6V at full load and is designed to maintain regulation during high-voltage transients and reverse-battery conditions. This regulator is housed in a 3-pin TO-220 through-hole package, making it suitable for high-power dissipation requirements.

Why Choose This Part

It offers superior protection with integrated reverse polarity, over-current, and over-temperature circuitry alongside a 60V load dump rating. The 1 percent initial output accuracy and fast transient response ensure stable power for sensitive digital logic even under fluctuating load conditions.

Applications

Automotive Power Distribution
Utilizes 60V transient protection and reverse-battery safety to provide stable 3.3V rails in vehicle environments.
High-Efficiency Linear Supplies
Functions as a high-current post-regulator for switching power supplies to reduce ripple while maintaining efficiency with low dropout.
Battery-Powered Industrial Tools
Provides a regulated 3.3V output from battery packs with a maximum input voltage up to 26V and low ground current.
