TOREX XC6412

XC6411/XC6412 Series
ETR0320_005
0.8uA Low Power Consumption Dual Voltage Regulator
■GENERAL DESCRIPTION
The XC6411/6412 series are highly precise, low noise, positive voltage LDO dual regulators manufactured using CMOS
processes. The series achieves very low supply current, 0.8μA / ch. (TYP.) and consists of a reference voltage source, an
error amplifier, a current foldback circuit, and a phase compensation circuit plus a driver transistor. SOT-25 package for the
XC6411P series, SOT-26 package for the XC6412B series and USP-6C package for the XC6412C series (preliminary) make
high density mounting possible. Therefore, the series is ideal for applications where high density mounting is required such
as in mobile equipment.
Output voltage of each regulators VR1 and VR2 is selectable in 100mV increments within a range of 0.9V to 5.0V by laser
trimming. The series is also compatible with low ESR ceramic capacitors, which give added output stability. VR1 and VR2
are completely isolated. For this, a cross talk between each channel, which causes a problem during load fluctuations, can be
greatly reduced, and the stabilized voltage can be supplied. The current limiter's foldback circuit also operates as a short
protect for the output pin.

*Preliminary
* The dissipation pad for the USP-6C 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 (pin # 5).

■OPERATIONAL EXPLANATION
<Output Voltage Control>
The voltage, divided by resistors R11 & R12 for a regulator 1 and R21 & R22 for a regulator 2 is compared with the internal
reference voltage by the error amplifier. These resistors are connected to the VOUT pin. The P-channel MOSFET, which is
connected to the VOUT pin, is then driven by the subsequent output signal. The output voltage at the VOUT pin is controlled and
stabilized by a system of negative feedback. The current limit circuit operates when the load current reaches the current limit
level.

<Dual Inputs>
The power input voltage pin of the regulator 1 and regulator 2 in the XC6411P/XC6412C series operate independently of
absolute, which makes the circuit structure efficiently.
<Short Protection Circuit>
The XC6411P/6412 series’ regulator offers short-circuit protection by means of a built-in 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
voltage pin is shorted, a current of about 50mA flows.
<EN2 Pin>
The regulator 2’s internal circuitry can be operated or shutdown via the signal from the EN2 pin with the XC6412 series. In so
doing the regulator 1 maintains an operational state constantly. In shutdown mode, output at the VOUT2 pin will be pulled down
to the VSS level via R21 & R22. Note that the XC6412 series’ regulator is “High Active/No Pull-Down”, operations will become
unstable with the EN2 pin open. We suggest that you use this IC with either a VIN voltage or a VSS voltage input at the EN2 pin.
If this IC is used with the correct specifications for the EN pin, the operational logic is fixed and the IC will operate normally.
However, supply current may increase as a result of through current in the IC's internal circuitry.
■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.
3. As for the XC6412 series, internally achieved phase compensation makes a stable operation of the IC possible even when
there is no output capacitor (CL). In order to stabilize the VIN’s voltage level, we recommend that an input capacitor (CIN) of
about 0.1 to 1.0μF be connected between each VIN pin and the VSS pin. Moreover, during transient response, so as to
prevent an undershoot or overshoot, we recommend that the output capacitor (CL) of about 0.1 to1.0μF be connected
between each VOUT pin and the VSS pin. However, please wire the input capacitor (CIN) and the output capacitor (CL) as
close to the IC as possible.
4. The XC6412C series (USP-6C package) is under development.
