Product Details

LM78 Series Linear Voltage Regulators, Fairchild Semiconductor

The LM78xx family, three terminal linear voltage regulator by Fairchild Semiconductor is a fixed voltage regulator which can be used in a range of applications. The positive fixed voltage regulator requires no external components and they incorporate internal thermal overload protection and current limiting plus safe area compensation.

Fixed Output Voltage range 5 V up to 24 V
Output Current: 1A
Internal current limiting
Thermal shutdown
Safe operating area protection
TO220 package


Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents.
