The LM78XX series of three-terminal positive regulators
is available in the TO-220 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 operating area protection. If
adequate heat sinking is provided, they can deliver over
1 A output current. Although designed primarily as fixedvoltage regulators, these devices can be used with external components for adjustable voltages and currents.
Output Current up to 1 A
Output Voltages: 5, 6, 8, 9, 10, 12, 15, 18, 24 V
