LM7812 Datasheet – 1A, 12V, Voltage Regulator ( PDF )

Part Number: LM7812, LM7812CT, LM7812ACT

Function : 3-TERMINAL 1A, 12V, Positive Voltage Regulator

Package: TO-220 type

Manufacturer: Fairchild




This is 1A, 12V, Positive Voltage Regulator.

The LM78XX series, LM7812 of three terminal positive regulators are available in the TO-220 package and with several fixed output voltages, making them useful in a wide range of applications. Each type employs internal current limiting, thermal shut down and safe operating area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents.
