This document is the datasheet of MC78M00/MC78M00A series positive voltage regulators.
The MC78M00 series are three‑terminal medium‑current positive voltage regulators designed for on‑card voltage regulation. They feature internal current limiting, thermal shutdown, and safe‑area compensation, allowing up to 500 mA output current with adequate heatsinking.
The devices are offered in TO‑220 (case 221A) and DPAK (case 369) packages, operate over a junction temperature range of –40 °C to +125 °C, and include specifications such as dropout voltage, ripple rejection, and thermal resistance.
| Maximum Output Current | 500 mA |
|---|---|
| Junction Temperature Range | ‑40 °C to +125 °C |
| Thermal Resistance (J‑to‑Air) | 70 °C/W |
| Dropout Voltage | 2.0 V |
The regulator can deliver up to 500 mA of output current when properly heatsunk.
It operates from –40 °C up to +125 °C junction temperature.
The typical dropout voltage is 2.0 V.
