3-Terminal 1A Positive Voltage Regulator

GENERAL DESCRIPTION

The LM7812 series 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.
