XC6404 Series

High Current, High Speed LDO Regulators,

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

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 5.5V and the LDO output voltage is selectable within a range of

0.9V to 5.1V, 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 (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).
