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
P-DSO-20-6
operating voltage is 45 V. The output is able to drive a 150 m A 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 P-DSO-14-4 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.

Frequently Asked Questions
How is reset delay time set?
It can be selected by connecting the Reset Delay pin to GND via an external capacitor.
What are the maximum operating voltagles and load capabilities for TLE 4269?
The maximum P-DSO-20-6 operating voltage is 45 V, and the output is able to drive a 150 mA load.
Does this regulator offer overcurrent protection or thermal monitoring?
It provides short circuit protection, and thermal shutdown switches the output off if the junction temperature exceeds 150 °C.
How can I change the low reset detection voltage (V)?
The Q reset threshold voltage can be decreased by external connection of a voltage divider.
