The XC6403/04 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 5.6V and the LDO output voltage is selectable
within a range of 0.9V to 5.6V (XC6403) 0.9V to 5.1V (XC6404),
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
(XC6403/04 A to C series). The whole IC can be put in to
stand-by mode via the CE function with the XC6403/04D series
(semi-custom). In the stand-by mode, power consumption is
greatly reduced. The XC6403/04A and B series features the
toggle operation function. The regulator output can be OFF when
the XC6403/04B series detects voltage (semi-custom). The
XC6403/04E series can monitor another power source by using
the V
SEN
pin (semi-custom). The XC6403/04F series can
delay the detector output: the delay time can be controlled by
the use of an external capacitor (semi-custom).
