Product Introduction

Overview

The MC78M09BDTG is a positive linear voltage regulator from onsemi, part of the MC78M00/MC78M00A series. This regulator is similar to the popular MC7800 Series but is specified for half the output current. It is designed for local, on-card voltage regulation and features internal current limiting, thermal shutdown circuitry, and safe-area compensation for the internal pass transistor, making it robust under various operating conditions.

The MC78M09BDTG provides a maximum output current of 500 mA with adequate heatsinking and is available in DPAK-3 and TO-220 packages. It offers high accuracy options and is suitable for industrial applications.
