Description

The OPTIREG™ linear TLE4263-2GS is a monolithic integrated very low dropout voltage regulator in a SMD

package PG-DSO-8, especially designed for automotive applications. An input voltage up to 45 V is regulated

to an output voltage of 5.0 V. The component is able to drive loads up to 180 mA. The IC is short-circuit proof

by the implemented current limitation and has an integrated overtemperature shutdown.

It additionally provides features like power-on and undervoltage reset with adjustable reset threshold, a

watchdog circuit for monitoring a connected microcontroller and an inhibit input for enabling or disabling the

component.

The reset output RO is set to “low” in case the output voltage falls below the reset switching threshold VQ,rt.

This threshold can be decreased down to 3.5 V by an external resistor divider. The power-on reset delay time

can be programmed by the external delay capacitor CD.
