XC6403/XC6404 Series ETR10002-005 High Current, High Speed LDO Regulators, Voltage Detector Function - GENERAL DESCRIPTION The XC6403/XC6404 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 pensation circuit plus a driver transistor. Detect voltage is selectable in 100m V 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 100m V increments. The series is also patible 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/XC6404 A, 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/ XC6404A series Features the toggle operation function. The regulator output can be OFF when the XC6403/04B series detects voltage (semi-custom). The XC6403/XC6404E series can monitor another power source by using the VSEN pin (semi-custom). The XC6403/ XC6404F series can delay the detector output: the delay time can be controlled by the use of an external capacitor...
