3-TERMINAL 1A POSITIVE

VOLTAGE REGURATORS
The KA78XX series of three-terminal positive
regulators are available in the TO-220 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.
