MC78XXE/LM78XXE/MC78XXAE
3-Terminal 1A Positive Voltage Regulator
Features
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.
Output Current up to 1A
Output Voltages of 5, 6, 8, 9, 12, 15, 18, 24V

Notes:
(1) To specify an output voltage. substitute voltage value for "XX." A common ground is required between the input and the
Output voltage. The input voltage must remain typically 2.0V above the output voltage even during the low point on the input
ripple voltage.
(2) CI is required if regulator is located an appreciable distance from power Supply filter.
(3) CO improves stability and transient response.
