XC6402
Series
High Current, High Speed LDO Regulators, Voltage Detector Function
ETR1001_001
The XC6402 series are precise, low noise, high current, positive voltage low dropout regulators with built-in voltage detector.
They are fabricated using Torex’s CMOS process. The series features a voltage reference, an error amplifier, a current
limiter, a voltage detector and a phase compensation circuit plus a driver transistor.
The output voltage of the LDO and detect voltage of the detector is selectable in 50mV increments within the range of 0.8V to
5.0V. With a low ON resistance driver transistor built-in, batteries can be used until input-output voltage differential is minimal
and can accordingly be used for a longer time.
The series is also compatible with low ESR ceramic capacitors which give added output stability. The series provides options
to the user to select from a variety of circuit features, such as detector monitoring, detector output logic, EN pin input logic,
and internal pull-up / down resistance (semi-custom). The IC's internal regulator circuit can be placed in stand-by mode via
the EN function (XC6402C series). In the stand-by mode, power consumption is greatly reduced. The XC6402F series
offers the option of a delay on the detector output: the delay time can be controlled by the use of an external capacitor.

CONFIGURATION
USP-6B (BOTTOM VIEW)
*The dissipation pad for the USP-6B package
should be solder-plated in recommended mount
pattern and metal masking so as to enhance
mounting strength and heat release.
If the pad needs to be connected to other pins, it
should be connected to the V
SS
pin.
