GENERAL DESCRIPTION
The XC6403 series are highly precise, low noise, 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 5.6V, 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, and internal pull-up / down resistance.
The IC's internal regulator circuit can be placed in stand-by mode via the
EN function (XC6403 A to C series). The whole IC can be put in to
stand-by mode via the CE function with the XC6403D series (semi-
custom). In the stand-by mode, power consumption is greatly reduced.
The XC6403 A and B series features the toggle operation function. The
regulator output can be OFF when the XC6403B series detects voltage
(semi-custom).
The XC6403E series can monitor another power source by using the
VSEN pin (semi-custom).
The XC6403F series can delay the detector output: the delay time can be
controlled by the use of an external capacitor (semi-custom).
