The high current regulated output features fault
protection against over voltage as well as a thermal
shutdown feature. If the input voltage rises above 33V (load
dump), the high current output shuts down automatically.
The internal circuitry is thus protected and the IC is able to
survive higher voltage transients than might otherwise be
expected. The thermal shutdown of the high current output
effectively guards against overheating of the die since this
section of the IC is the principle source of power dissipation
on the chip.
ON/OFF
SWITCH
The ON/OFF pin is a high impedance low current
switch that controls the main output voltage (pin 2). This is
directly compatible with all 5 volt logic families. For use
with open collector logic outputs, a 100Kresistor from this
pin to a 5V supply, such as Pin 5, is required.
