3-Terminal 1 A Positive Voltage Regulator

Fairchild Semiconductor 

LM78XX/LM78XXA

3-Terminal 1A Positive Voltage Regulator

April 2010

Features

• Output Current up to 1A

• Output Voltages of 5, 6, 8, 9, 10, 12, 15, 18, 24

• Thermal Overload Protection

• Short Circuit Protection

• Output Transistor Safe Operating Area Protection

General Description

The LM78XX 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 pro-

tection, 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 com-

ponents to obtain adjustable voltages and currents.
