该系列包括参考电压源、误差放大器和相位补偿电路。CE功能通过输入低电平信号使整个电路处于待机状态。输出电压可在0.80V~5.00V范围内选择,增量为0.05V,使用工厂设置的激光微调技术。
限流器的折回电路还用作短路保护和输出引脚处的输出限流器。
该系列仅以8uA的低功耗实现快速响应。此外,该系列具有低压降电压特性,在IOUT=100mA和Vout=5.0V时为330V。
The 矽源特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.
