The TX6221 series is a high accuracy, low noise, high speed, low dropout CMOS regulator with high ripple rejection.

    The series includes a reference voltage source, an error amplifier, and a phase compensation circuit. The CE function enables the entire circuit to be in stand-by state by by inputting low level signal. Output voltage is selectable in 0.05V increments within a range of 0.80V~5.00V, using the laser trimming technology set in factory.

    The current limiter’s fold-back circuit also operates as a short circuit protection and an output current limiter at the output pin.

    The series achieves a fast response with only 8uA of low power consumption. Also the series has low dropout voltage characteristics, which is 330mV at IOUT=100mA and Vout=5.0V.
