Rev. 1.0.0
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 A r ea 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 sig ne d pr i mar i ly as fi x e d volt age
regulators, these devices can be used with external
components to obtain adjustable voltages and currents.
