Taiwan Semiconductor TQL82x 200mA Low-Dropout Linear Regulators

Taiwan Semiconductor TQL82x 200mA Low-Dropout Linear Regulators are high-performance low-dropout linear regulators for 3.3V or 5V with an input range of 3V to 50V and low quiescent 30μA. The TQL82x provides 2% output voltage accuracy and 200mA maximum driving current and is suitable for automotive or other supply systems. Each TQL82x requires one small ceramic capacitor of 1μF to exhibit fast regulation and good stability. It also 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 an automotive system.

The Taiwan Semiconductor TQL82x has an enable function to switch ON and OFF for power dissipation. It also has other protection functions such as thermal shutdown and current-limit that protect against immediate damage.
