Description

The 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 XC6404 includes high ripple rejection and low dropout voltage, and the XC6404 features a voltage reference, an error amplifier, a current limiter and a phase compensation circuit plus a driver transistor.

Detect voltage of XC6404 is selectable in 100mV increments within the range of 0.9V to 5.5V and the LDO output voltage is selectable within a range of 0.9V to 5.1V, also in 100mV increments.

The XC6404 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 XC6404 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 XC6404's internal regulator circuit can be placed in stand-by mode via the EN function (XC6404 A to C series).  The whole IC can be put in to stand-by mode via the CE function with the XC6404D series (semi-custom).  In the stand-by mode, power consumption is greatly reduced.
The XC6404A and B series features the toggle operation function.  The regulator output can be OFF when the XC6404B series detects voltage (semi-custom).

The XC6404E series can monitor another power source by using the VSEN pin (semi-custom).

The XC6404F series can delay the detector output: the delay time can be controlled by the use of an external capacitor (semi-custom).
