Functional Description
This device is a voltage regulator with a fixed 5-V
output, e.g. in a P-DSO-8-1 package. The maximum
operating voltage is 45 V. The output is able to drive a
150 mA load. It is short circuit protected and the
thermal shutdown switches the output off if the junction
temperature is in excess of 150 °C. A reset signal is
generated for an output voltage of VQ < 4.6 V. The
reset threshold voltage can be decreased by external
connection of a voltage divider. The reset delay time
can be set by an external capacitor. Reset and sense
output have integrated pull up resistors. If the
integrated resistors are not desired TLE 4279 can be
used. It is also possible to supervise the input voltage
by using an integrated comparator to give a low voltage
warning.
