MC78XXE/LM78XXE/MC78XXAE
3-Terminal 1A Positive Voltage Regulator
Features
• Output Current up to 1A
• Output Voltages of 5, 6, 8, 9, 12, 15, 18, 24V
• Thermal Overload Protection
• Short Circuit Protection
• Output Transistor Safe Operating Area Protection
Description
The MC78XXE/LM78XXE/MC78XXAE 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 operating 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.

Note:
1. Load and line regulation are specified at constant junction temperature. Changes in VO due to heating effects must be taken
into account separately. Pulse testing with low duty is used.
2. These parameters, although guaranteed, are not 100% tested in production.
