■GENERAL DESCRIPTION
■FEATURES
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.
Maximum Output Current
: More than 500mA
(600mA limit)
(2.5V≦VROUT≦4.9V)
: 200mV (IROUT=100mA)

Operating Voltage Range
VR Setting Output Voltage Range: 0.9V~ 5.1V
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).
