TLE4263-2ES is a monolithic integrated very low dropout voltage regulator in a SMD package PG-DSO-8 exposed pad, 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 over temperature 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 V Q,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 C D. The watchdog circuit provides a monitoring function for microcontrollers: At missing pulses on the watchdog’s input W the reset output RO is set to “low”. The trigger time for the watchdog pulses can be set by the external capacitor C D. The IC can be switched off by the inhibit input, reducing the current consumption to typically 0 μA.
