Design Considerations
The KIA78MXX fixed voltage regulator series has
built-in thermal overload protection which prevents
the device from being damaged due to excessive
junction temperature.
The regulators also contain internal short-circuit
protection which limits the maximum output current,
and safe-area protection for the pass transistor which
reduces the short circuit current as the voltage across
the pass transistor is increased. Although the internal
power dissipation is automatically limited, the maximum
junction temperature of the device must be kept
below+150
in order to meet data sheet specifications.
An adequate heatsink should be provided to assure this

conditions (maximum input voltage and load current)
(or if no input filter capacitor is used).
if reliable performance is to be obtained.
** Optional for improved transient response.
