LM7912 Datasheet PDF

●The LM7912CT is a fixed output, three terminal negative regulator in 3 pin TO-220 package. This regulator employs internal current limiting safe area protection and thermal shut down for protection against overload conditions. Low ground pin current of LM7912CT allows output voltage to be easily boosted above the preset value with resistor divider. Low quiescent current of this regulator ensures good regulation in voltage boosted mode. Bypass capacitors are necessary to stable the operation of LM7912CT over input voltage and output current ranges.

● Fixed output voltage is -12V

● 1.5A output current

● Input voltage range from -14.5V to -35V

● Dropout voltage is 1.1V at 1A output current

● High ripple rejection

● 4% tolerance on preset output voltage

● Operating temperature range 0°C to 125°C

●This device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to MOS gates.
