Overview
The MC78L05ACPREG is part of the MC78L00A Series of linear voltage regulators produced by onsemi. These regulators are designed to be inexpensive and easy to use, making them suitable for a wide range of applications that require a regulated supply of up to 100 mA. They are known for their ruggedness, featuring internal current limiting and thermal shutdown. This series offers a significant performance advantage over traditional zener diode-resistor combinations by reducing output impedance and quiescent current.
