Functional Description

This device is an automotive suited voltage regulator with

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

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.
