KA78XX/KA78XXA

3-Terminal 1A Positive Voltage Regulator

Features

• Output Current up to 1A

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

• Thermal Overload Protection

• Short Circuit Protection

• Output Transistor Safe Operating Area Protection

Description

The KA78XX/KA78XXA series of three-terminal positive regulator are available in the TO-220/D-PAK package and with several fix ed outp ut voltage s, makin g them usef ul in a wide range of applications. Each type employs internal current limiting, thermal shut down and safe operating area protection , making it essen tially indestruc tible. If adequa te heat sinking is provided, they can deliver over 1A output current. Although de signed primarily as fixed vol ta ge regulators, these devices can be used with external components to obtain adjustable voltages and currents.
