2017年11月23日 · LM7912 belongs to the family of Voltage regulators. The name “79” indicates negative and the term “12” indicates the voltage. So “7912” means that this IC will regulate a negative 12V for your projects. You can also check on 78 series for positive voltage regulators.

Low ground pin current of the LM79XX series allows output voltage to be easily boosted above the preset value with a resistor divider. The low quiescent current drain of these devices with a specified maximum change with line and load ensures good regulation in the voltage boosted mode. Figure 1.

These regulators can provide local on-card regulation, eliminating the distribution problems associated with single point regulation; furthermore, having the same voltage option as the L7800 positive standard series, they are particularly suited for split power supplies.

LM7912 is a three-terminal negative 12 volts voltage regulator IC. Most of the applications need both positive and negative voltages for their operation. The negative voltages should be stable otherwise they can damage the circuit or reduce the life of components used in the circuit.
