KA78XX/KA78XXA

3-Terminal 1A Positive Voltage Regulator

Features

Description

• 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

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.

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.
