XC6402 Series
ETR1001_001
High Current, High Speed LDO Regulators, Voltage Detector Function
■GENERAL DESCRIPTION
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.

■PIN 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 VSS pin.

■OPERATIONAL EXPLANATION
<Output Voltage Regulator Control>
The voltage, divided by resistors R1 & R2 which are connected to the VROUT pin is compared with the internal reference
voltage by the error amplifier. The P-channel MOSFET, which is connected to the VROUT pin, is then driven by the
subsequent output signal. The output voltage at the VROUT pin is controlled & stabilized by negative feedback. The current
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 VROUT pin or the
VIN pin, as well as monitoring the voltage of the internal reference voltage source via the comparator.
The VDSEN pin has options (please refer to the Selection Guide, item 2).
A 'High' or 'Low' signal level can be output from the VDOUT pin when the VD pin voltage level goes below the detect voltage.
The VD output logic has options (please refer to the Selection Guide, item 3). As VDOUT is an open-drain N-channel
output, a pull-up resistor of about 220kΩ is needed to achieve a voltage output. Because of hysteresis at the detector
function, output at the VDOUT 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 VROUT pin (from another power
source), the VDOUT pin will be high impedance mode, and the pull 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 VDOUT voltage when releasing voltage. The
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 (VROUT) and the VSS pin. Please use
an output capacitor (CL) with a capacitance, based on 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.

<Current Limiter, Short-Circuit Protection>
The XC6402 series regulator offers a combination of current limit and circuit protection by means of a built-in fixed current limiter
circuit and a foldback circuit. When the load current reaches the current limit level, the fixed current limiter circuit operates and
output voltage drops. As a result of this drop in output voltage, the foldback circuit operates, the output voltage drops further and
output current decreases. When the output pin is shorted, a current of about 30mA flows.

■OPERATIONAL EXPLANATION (Continued)
<EN Pin>
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 VROUT pin will be pulled down to the VSS level via R1 & R2. Note that as the XC6402*E to K types of
the XC6402C series are 'High Active / No Pull-Down' and XC6402*R to U types of the XC6402C series are 'Active LOW / No
Pull-Up', operations will become unstable with the EN pin open (See the chart below).

XC6402C E ~ K

XC6402C L ~ P

We suggest that you use this IC with either a VIN voltage or a VSS voltage input at the EN pin. If this IC is used with the
correct specifications for the EN pin, the IC will operate normally. However, 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 ratings be
exceeded.
2. Where wiring impedance is high, operations may become unstable due to noise and/or phase lag depending on output
current. Please strengthen VIN and VSS wiring in particular.
3. Please wire the input capacitor (CIN) and the output capacitor (CL) as close to the IC as possible.
Should rapid input fluctuation or load fluctuation occur, please increase the capacitor value such as CIN or CL to stabilize
the operation.
