The MC78M15ACTG is an adjustable 3-terminal positive voltage regulator with a 1.5A output current rating, from the MC78XX series, manufactured by ON Semiconductor. This device provides an output voltage that can be set from 1.2V to 37V, with a minimum 0.2% accuracy, by external resistors. It operates over an input voltage range of 5V to 40V, has a thermal shutdown feature, and is housed in a TO-220 package.
