Product Introduction

Overview

The MC78M09BDTRKG is a part of the MC78M00/MC78M00A Series of positive linear voltage regulators produced by onsemi. These regulators are identical to the popular MC7800 Series devices but are specified for only half the output current, which is 500 mA. They are designed for local, on-card voltage regulation and feature internal current limiting, thermal shutdown circuitry, and safe-area compensation for the internal pass transistor, making them remarkably rugged under most operating conditions.
