ONMC7915CTG

Overview

The MC7915CTG is a monolithic negative voltage regulator designed to provide a fixed -15V output at currents up to 1.5A. It utilizes internal current limiting, thermal shutdown, and safe-area compensation to ensure robust operation in demanding power supply circuits. This through-hole TO-220 device is a standard solution for creating split-rail power supplies when paired with a positive complementary regulator.

Why Choose This Part

The MC7915CTG requires no external components for basic operation, significantly reducing PCB complexity and footprint. It features a high Power Supply Rejection Ratio (PSRR) of 60dB at 120Hz and includes comprehensive internal protection against thermal overloads and short circuits.

Applications

Getting Started

To implement this regulator, ensure a minimum input voltage of -17.5V is maintained and place a 1.0uF tantalum or 10uF electrolytic capacitor on the output for improved stability. Use a heatsink if the power dissipation (input-to-output voltage differential multiplied by current) exceeds the TO-220 package's ambient thermal rating.
