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

3-TERMINAL 1A POSITIVE

VOLTAGE REGULATORS

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

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

adjustable voltages and currents.

FEATURES

• 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
