TECHNICAL DATA

THREE TERMINAL POSITIVE VOLTAGE REGULATORS

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

FR78MXX 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.

Design Considerations

The FR78MXX fixed voltage regulator series has

built-in thermal overload protection which prevents

the device from being damaged due to excessive

junction temperature.

OUT

0.1�F

0.33�F

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

FR78MXX

GND

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

limit is not exceeded under worst-case operating

conditions (maximum input voltage and load current)

if reliable performance is to be obtained.

* Required if regulator input is more then 4 inches

form input filter capacitor.

(or if no input filter capacitor is used).

** Optional for improved transient response.
