2017年11月23日 · The LM7912 is a -12V Voltage regulator IC. Meaning it will provide a constant output voltage of -12V when the input voltage is between -14.5V to -27V. A very basic Voltage regulator circuit is shown below.

Description: LM79XX Series 3-Terminal Negative Regulators. Manufacturer: National Semiconductor (TI).

LM7912 IC is a negative voltage regulator supply negative voltages. It consists of three pins and has a fixed output voltage of -12V. It is used in case of fluctuating inputs to stable the output,

These regulators employ internal current limiting safe area protection and thermal shutdown for protection against virtually all overload conditions. Low ground pin current of the LM79XX series allows output voltage to be easily boosted above the preset value with a resistor divider.

LM 7912 belongs to the 79xx family of voltage regulator ICs and is very commonly used in such power supplies where 12V negative voltage output is required. 7912 is almost a standalone regulator IC.
