MCHPMIC2937A-5.0WT

Overview

The MIC2937A-5.0WT is a 750mA high-current, low-dropout voltage regulator featuring a fixed 5V output and high accuracy. Designed for efficiency, it maintains a low quiescent current of 160uA at light loads and provides robust protection against input transients up to 60V and reverse battery conditions down to -20V. Its TO-220 package makes it ideal for through-hole applications requiring significant power dissipation and high reliability.

Why Choose This Part

This regulator offers an extremely tight 1 percent output accuracy and excellent load/line regulation. Its ability to withstand high-voltage transients without external surge protection simplifies the bill of materials in harsh environments. The device also features thermal and short-circuit current limiting to ensure long-term reliability.

Applications

Getting Started

For implementation, place a 10uF or larger capacitor (with ESR under 5 ohms) on the output for stability and a 0.1uF ceramic capacitor on the input if the device is far from the main filter. Ensure the TO-220 tab is properly heatsinked if operating near the 750mA limit with a high input-to-output voltage differential. No external resistors are required since this is a fixed 5V version.
