XC6405 Series

High Current, High Speed LDO Regulators,

The XC6405 series are precise, low noise, high speed, 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 (XC6405 A to C series). The whole IC can be put in to

stand-by mode via the CE function with the XC6405D series (semi-

custom). In the stand-by mode, power consumption is greatly reduced.

The XC6405 A and B series features the toggle operation function. The

regulator output can be OFF when the XC6405B series detects voltage

(semi-custom).

The XC6405E series can monitor another power source by using the

VSEN pin (semi-custom).

The XC6405F series can delay the detector output: the delay time can be

controlled by the use of an external capacitor (semi-custom).
