XC6402 Series
ETR1001_003
High Current, High Speed LDO Regulators, Voltage Detector Function
■GENERAL DESCRIPTIO N
The XC6402 series are precise, low noise, high current, positive v oltage lo w dropout regul ators with built-in v oltage 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 intern al regulator circuit can be placed in stand-by mode vi a
the EN function (XC6402C series). In the stand-by mode, power consumption is greatly reduced. T he 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.

PIN NAME FUNCTION
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.

■OPERATIONAL EXPLANATION
<Output Voltage Regulator Control>
The voltage, divided by resistors R1 & R2 which are conne cted to the V
voltage by the error amplifier. The P-channel MOSFET, which is connected to the V
subsequent output signal. The output voltage at the V
limit circuit and short circuit protection operate in relation to the level of output current. Further, the voltage regulator's
internal circuitry can be shutdown via the EN pin's signal.
<Detector Function with the XC6402 Series>
The series' detector function monitors the voltage divided by resistors R3 & R4 which are connected to the V
V
IN pin, as well as monitoring the voltage of the internal reference voltage source via the comparator.
The V
DSEN pin has options (please refer to the Selection Guide, item 2).
A 'High' or 'Low' signal level can be output from the V
The VD output logic has options (please refer to the Selection Guide, item 3). As V
output, a pull-up resistor of about 220kΩ is neede d to achieve a voltage output. Because of hysteresis at the detector
function, output at the V
DOUT pin will invert when the detect voltage level increases above the release voltage (105% of the
detect voltage).
For the XC6402C type, in stand-by, if a voltage of the recovery voltage is present at the V
source), the V
DOUT pin will be high impedance mode, and the pu ll up voltage will be output at VDOUT. By connecting the
Cdelay pin to a capacitor (Cd), the XC6402F series can apply a delay time to V
delay time can be calculated from the internal resistance, Rdelay (2MΩ TYP. fixed) and the value of Cd as per the following
equation.
Delay Time = Cdelay x Rdelay x 0.7

<Low ESR Capacitors>
With the XC6402 series regulator, a stable output voltage is achievable even if low ESR capacitors are used, as a phase
compensation circuit is built-in to the regulator. In order to ensure the effectiveness of the phase compensation, we suggest
that an output capacitor (CL) be connected as close as possible, between the output pin (V
an output capacito r (CL) with a ca pacitance, based o n the chart below. We also suggest an input capacitor (CIN) of 1μF :
this should be connected between VIN and VSS in order to stabilize input power source.

output voltage drops. As a result of this drop in output voltage, the foldback circuit operates, the output voltage drops further and

The IC's internal regulator circuitry can be shut down via the signal from the EN pin with the XC6402C series. In shutdown
mode, output at the V
the XC6402C series are 'High Active / No Pull-Down' and XC6402*R to U types of the XC6402C series are 'Active LOW / No

We suggest that you use this IC with either a V
correct specifications for the EN pin, the IC will operate normally. Ho wever, supply current may increase as a result of
through current in the IC's internal circuitry if a voltage other than VIN or VSS is applied.
■NOTES ON USE
1. Please use this IC within the stated absolute maximum ratings. The IC is liable to malfunction should the ratin gs be
exceeded.
2. Where wiring impedance is high, operations may become unstable due to noise and/or phase lag depen ding on output
