XC6403/XC6404Series  
ETR1002_003  
High Current, High Speed LDO Regulators, Voltage Detector Function  
GENERAL DESCRIPTION  
The XC6403/04 series are highly precise, low noise, high current, positive voltage low dropout regulators with built-in voltage  
detector. They are fabricated using Torex’s CMOS process. Performance features of the series includes high ripple rejection  
and low dropout voltage, and the series features a voltage reference, an error amplifier, a current limiter and a phase  
compensation circuit plus a driver transistor.  
Detect voltage is selectable in 100mV increments within the range of 0.9V to 5.6V and the LDO output voltage is selectable  
within a range of 0.9V to 5.6V (XC6403) 0.9V to 5.1V (XC6404), also in 100mV increments. The series is also compatible with  
low ESR ceramic capacitors which give added output stability. This stability can be maintained even during load fluctuations  
due to the excellent transient response of the series. The current limiter's foldback circuit also operates as a short circuit  
protection for the output current limiter and the output pin. The series provides options to the user to select from a variety of  
circuit features, such as detector monitoring, detector output logic, CE and EN pin input logic, internal pull-up / down  
resistance, and power ready. The IC's internal regulator circuit can be placed in stand-by mode via the EN function  
(XC6403/04 A to C series). The whole IC can be put in to stand-by mode via the CE function with the XC6403/04D series  
(semi-custom). In the stand-by mode, power consumption is greatly reduced. The XC6403/04A and B series features the  
toggle operation function. The regulator output can be OFF when the XC6403/04B series detects voltage (semi-custom). The  
XC6403/04E series can monitor another power source by using the VSEN pin (semi-custom). The XC6403/04F series can  
delay the detector output: the delay time can be controlled by the use of an external capacitor (semi-custom).
