KA78XXE/KA78XXAE 3-Terminal 1A Positive Voltage Regulat
Sep 2009
KA78XXE/KA78XXAE
3-Terminal 1A Positive Voltage Regulator
Features
Output Current up to 1A
Output Voltages of 5, 6, 8, 9, 10, 12, 15, 18, 24V
Thermal Overload Protection
Short Circuit Protection
Output Transistor Safe Operating Area Protection
Description
The KA78XXE/KA78XXAE series of three-terminal posi-
tive regulator are available in the TO-220/D-PAK package
and with several fixed output voltages, making them use-
ful in a wide range of applications. Each type employs
internal current limiting, thermal shut down and safe
operating area protection, making it essentially inde-
structible. If adequate heat sinking is provided, they can
deliver over 1A output current. Although designed pri-
marily as fixed voltage regulators, these devices can be
used with external components to obtain adjustable volt-
ages 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.
