TQL820CA14V50 Taiwan Semiconductor 200mA, Low-I 40A Low-Dropout Regulator Q with Enable, Reset, Watchdog Functions DESCRIPTION FEATURES The TQL820CA14V50 is a high-performance low AEC-Q100 qualified with the following results: dropout voltage regulator for 5V with input range of 3V - Device temperature grade 1: -40C to 125C to 50V and low quiescent 40A. TQL820CA14V50 - Device HBM ESD classification level H2 provides 2% output voltage accuracy and 200mA - Device CDM ESD classification level C3 maximum driving current and is suitable for automotive 3V to 50V Input Voltage Range or other supply systems. 5V Fixed Output Voltage TQL820CA14V50 just requires one small ceramic 70mV 100mA Low Dropout Voltage capacitor of 1F to exhibit fast regulation and good 200mA Output Current stability. And it shows very low-dropout voltage with Typical 40A Low Quiescent Current 70mV in 100mA-load and 110mV in 200mA-load. The Typical 2% Output Voltage Accuracy start operating voltage is 3V which is suitable to 1F Ceramic Output Stable Capacitor cranking condition of automotive system. Programmable Delayed Reset timing at Power-On The device has enabled function to switch ON and OFF Adjustable Reset Threshold Voltage for power dissipation. And there is Reset function to Flexible Watch-dog Timing and Current Dependent monitor output voltage for UVLO reset and power-ON Deactivation delay reset with adjustable lower reset threshold Output Current Limit function. The built-in watchdog function monitors Enable, Under-voltage Reset. microcontrollers operation with flexible timings. And Over Temperature Protection other protection functions such as thermal-shutdown RoHS Compliant and current-limit are against immediate damage.
