Output Current up to 1A
Output Voltages of 5, 12V
Thermal Overload Protection
Short Circuit Protection
Output Transistor Safe Operating Area Protection
The MC78XXE series of three terminal positive regulators
are available in the 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 operating area protection, mak-
ing 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.
