P-DSO-8-3, -6, -7, -8, -9
Functional Description
This device is an automotive suited voltage regulator with
P-DSO-14-3, -8, -9, -11, 14
a fixed 5-V output, e.g. in a PG-DSO-8-16 package. The
maximum operating voltage is 45 V. The output is able to
drive 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 V_Q < 4.65 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. If the application requires pull-up
resistors at the logic outputs (Reset, Sense Out) the TLE 4269 with integrated resistors
can be used. It is also possible to supervise the input voltage by using an integrated
comparator to give a low voltage warning.
