TQL851CSV33 Taiwan Semiconductor 50V, 500mA, Low-IQ 30μA Low-Dropout Linear Regulator with Enable DESCRIPTION The TQL851CSV33 is a high-performance low dropout linear regulator for 3.3V with input range of 3V to 50V and low quiescent 30μA. TQL851CSV33 provides 2% output voltage accuracy and 500mA maximum driving current and is suitable for automotive or other supply systems. TQL851CSV33 just requires one small ceramic capacitor of 1μF to exhibit fast regulation and good stability. And it shows very low dropout voltage with typical 60mV in 100mA-load and 150mV in 250mAload. The start operating voltage is 3V which is suitable to cranking condition of automotive system. The device has an enable function to switch ON and OFF for power dissipation.
