THREE TERMINAL POSITIVE VOLTAGE REGULATORS

5V, 8V, 12V, 15V.

KIA78M

Series of three-terminal positive voltage regulators

employ built-in current limiting, thermal shutdown, and safe-operating

area protection which makes them virtually immune to damage from

output overloads. With adequate heatsinking, they can deliver in excess

of 0.5A output current.

FEATURES

Output current in excess of 0.5A.

No external components.

Internal thermal overload protection.

Internal short circuit current limiting.

Output transistor safe-area compensation.

Available in DPAK package.

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 * Required if regulator input is more then 4 inches

limit is not exceeded under worst-case operating form input filter capacitor.

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.
