Product Introduction

Overview

The MC78M05BDTT5G is a 500 mA positive linear voltage regulator from onsemi, part of the MC78M00/MC78M00A series. This regulator is similar to the popular MC7800 Series devices 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 MC78M05BDTT5G is available in several voltage options, but specifically, the '05' variant is set for a 5V output. It requires no external components and is available in Pb-free packages.
