KA78XX/KA78XXA
3-terminal 1A positive voltage regulator
Features
Description
• Output Current up to 1A
• Output Voltages of 5, 6, 8, 9, 10, 11, 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 cur-
rent limiting, thermal shut-down and safe operating area pro-
tection, 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) C is required if regulator is located an appreciable distance from power Supply filter.

(3) C improves stability and transient response.
