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 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.
