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
V
Q
< 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. 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.
