Functional Description

This device is an automotive suited voltage regulator with a fixed 5-V output, e.g. in a P-

DSO-8-3 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 VQ < 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.
