LM78XX (KA78XX, MC78XX) FIXED VOLTAGE REGULATOR (POSITIVE)

3-TERMINAL 1A POSITIVE

VOLTAGE REGULATORS

TO-220

The LM78XX series of three-terminal positive regulators 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 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

D-PAK

regulators, these devices can be used with external components to obtain

adjustable voltages and currents.

FEATURES

1: Input 2: GND 3: Output

· Output Current up to 1A

· Output Voltages of 5, 6, 8, 9, 10, 11, 12, 15, 18, 24V

· Thermal Overload Protection

· Short Circuit Protection

· Output Transistor SOA Protection
