LM7915 Regulator IC: Equivalent, Schematic and Datasheet

LM7915 is a fixed -15V voltage regulator IC. It belongs to the LM79xx series; this series contains a variety of different fixed output negative voltage regulators. All these regulators are built to provide a specific output voltage. 

The output voltage of the ICs in the LM79xx series can be checked by looking at the last two digits of the IC after LM79. LM7915 IC provides fixed -15V at the output with the output current of 1.5A, however for getting stable -15V output the input voltage should be 2V to 3V higher than -15V. 

Moreover for a 1.5A output current, a suitable should be required with the IC, or else the IC will continuously go shut down whenever the load is connected. 

LM7915 is a reliable IC to use in commercial equipment, the built-in thermal protection, overcurrent protection, and safe area protection circuitry make the IC robust and foolproof in a variety of wrong and uncertain situations.
