KA78XX/KA78XXA
3-Terminal 1A Positive Voltage Regulator
Features
Description
• 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
The KA78XX/KA78XXA series of three-terminal positive
regulator 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.

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.

Distributor and field sales
representatives
The KA78XX/KA78XXA series of three-
terminal positive regulator 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 in destructible. 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.
