Function

The LM78L12CMS is a linear voltage regulator in a TO-XX package with a wide range of output voltage options. The voltage regulator is used to provide a stable, steady, and constant output voltage to a load regardless of the input voltage level or current level. The device also features protection against overvoltage and overtemperature, as well as overcurrent protection.When input voltage is applied to the module, the device will compare the input voltage to the reference voltage, and output voltage is adjusted based on the voltage difference. This is done by switching devices that increase or decrease the voltage by a selectable amount at a controlled rate. The module has separate feedback loops for current and voltage regulation. When the output voltage drops below or exceeds a certain level, the device will kick into protection mode, preventing any damage from occurring.
