Data Sheet, Rev. 1.0, April 2008 TLE4263-2ES 5-V Low Dropout Voltage Regulator Automotive Power 5-V Low Dropout Voltage Regulator TLE4263-2ES 1 Overview Features Exposed Pad Package with Excellent Thermal Behaviour Output Voltage Tolerance ≤ ±2% Output Current up to 180 mA Very Low Standby Current Consumption Watchdog for Monitoring a Microprocessor Power-on and Undervoltage Reset with Programmable Delay Time Reset Low down to VQ = 1 V Adjustable Reset Threshold Very Low Dropout Voltage Output Current Limitation Reverse Polarity Protection Overtemperature Protection Wide Temperature Range from -40 °C up to 150 °C Input Voltage Range from -42 V to 45 V Suitable for Use in Automotive Electronics Green Product (RoHS compliant) AEC Qualified PG-DSO-8 exposed pad Description 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 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 ou...
