The XC6403CE85MR is a highly precise, low noise, high current, positive voltage low dropout regulator with built-in voltage detector. It is fabricated using Torex’s CMOS process. Performance features of the XC6403CE85MR includes high ripple rejection and low dropout voltage, and the XC6403CE85MR feature a voltage reference, an error amplifier, a current limiter and a phase compensation circuit plus a driver transistor. Detect voltage is 3.30V and the LDO output voltage is 3.00V. The XC6403CE85MR is also compatible with low ESR ceramic capacitor which give added output stability.This stability can be maintained even during load fluctuations due to the excellent transient response of the XC6403CE85MR. The current limiter's foldback circuit also operates as a short circuit protection for the output current limiter and the output pin. The IC's internal regulator circuit can be placed in stand-by mode via the EN function. In the stand-by mode, power consumption is greatly reduced.
