To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore (_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please email any questions regarding the system integration to Fairchild_questions@onsemi.com.

Block Diagram SERIES PASS ELEMENT SOA PROTECTION ERROR AMPLIFIER THERMAL PROTECTION CURRENT GENERATOR REFERENCE VOLTAGE STARTING CIRCUIT OUTPUT 3 GND 2 INPUT 1 Description The KA78XXE / KA78XXAE series of three-terminal posi- tive regulators is available in the TO-220 / D-PAK pack- age 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. If adequate heat sinking is provided, they can deliver over 1 A output current. Although designed primarily as fixed-voltage regulators, these devices can be used with external components for adjustable voltages and currents. 1 1. Input 2. GND 3.
