XC6411/XC6412
Series
0.8uA Low Power Consumption Dual Voltage Regulator
ETR0320_005
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 V

pin (pin # 5).
