XC6413/XC6414Series
ETR1004-003
High Current, High Speed LDO Regulators, Voltage Detector Function
■GENERAL DESCRIPTION
The XC6413/14 series are highly precise, low noise, positive voltage LDO regulators with voltage detector manufactured using
CMOS processes. Performance features of the series includes high ripple rejection and lo dropout 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 0.1V increments within a range of 0.9V ~ 6.0V and VR output voltage is selectable within a range of 0.9V ~
5.5V. 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 protect fro 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. The IC’s internal regulator circuit can be placed in stand-by mode via the EN function with the
XC6413/14A to C series. The whole IC can be placed in stand-by mode via the CE function with the XC6413/14D series
(semi-custom). In the stand-by mode, power consumption is greatly reduced. The XC6413/14A and B series features a
toggle operation function. The regulator output can be OFF when the XC6413/14B series detects voltage (semi-custom).
The XC6413/14E series can monitor another power source by using the VSEN pin (semi-custom). The XC6413/14F series
can delay the detector output. Delay time can be controlled by the use of an external capacitor (semi-custom).
