KA78XXE/KA78XXAE
3-Terminal 1A Positive Voltage Regulator
Features
Description
• Output Current up to 1A
• Output Voltages of 5, 6, 8, 9, 12, 15, 18, 24V
• Thermal Overload Protection
• Short Circuit Protection
• Output Transistor Safe Operating Area Protection
The KA78XXE/KA78XXAE series of three-terminal posi-
tive 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.

Notes:
1. To specify an output voltage. substitute voltage value for "XX." A common ground is required between the input and the Output
voltage. The input voltage must remain typically 2.0V above the output voltage even during the low point on the input ripple
voltage.
2. C is required if regulator is located an appreciable distance from power Supply filter.
