Overview
The MC78L08ACDR2G is a linear voltage regulator from onsemi, part of the MC78L00A Series. These regulators are known for their simplicity, low cost, and robust performance, making them suitable for a wide range of applications requiring a regulated supply of up to 100 mA. They feature internal current limiting and thermal shutdown, enhancing their reliability and ruggedness. No external components are necessary in many applications, and they offer a significant performance advantage over traditional zener diode-resistor combinations by reducing output impedance and quiescent current.
