The CXLD64323 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 3 3 0 m V a t I O U T = 1 0 0 m A a n d V o u t = 5 . 0 V .
