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.
