Low Dropout Regulator with Enable, Reset, Watchdog Functions: TQL820CA14V33_V50
The TQL820CA14V33_V50 series are high-performance low dropout voltage regulators for 3.3V and 5V with input ranges of 3V to 50V and low quiescent 40μA. TQL820CA14V33_V50 provides 2% output voltage accuracy and 200mA maximum driving current and is suitable for automotive or other supply systems.
TQL820CA14V33_V50 just requires one small ceramic capacitor of 1μF to exhibit fast regulation and good stability. It shows very low dropout voltage with 70mV in 100mA-load and 110mV in 200mA-load. The start operating voltage is 3V, which is suitable for the cranking condition of the automotive system.
The device has enabled function to switch ON and OFF for power dissipation. There is a reset function to monitor output voltage for UVLO reset and power-ON delay reset with an adjustable lower reset threshold function. The built-in watchdog function monitors the microcontroller’s operation with flexible timings. Other protection functions such as thermal shutdown and current limit are against immediate damage.
