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 pliant) - 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 ponent 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 ponent. 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....
