Product Introduction

Overview

The MC78M12CDTRKG is a 12V positive voltage regulator from onsemi, part of the MC78M00/MC78M00A and NCV78M00 series. These regulators are designed for local, on-card voltage regulation and are similar to the MC7800 series but with half the output current. They are known for their ruggedness and reliability under various operating conditions.

The MC78M12CDTRKG is available in a DPAK-3 package and is Pb-Free, making it suitable for a wide range of applications requiring stable and regulated voltage output.
