MC78XX (LM78XX) (KA78XX)
FIXED VOLTAGE REGULATOR (POSITIVE)
3-TERMINAL 1A POSITIVE
VOLTAGE REGULATORS
TO-220
The MC78XX 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 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.

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.
