XC6411/XC6412
Series
0.8μA Low Power Consumption Dual Voltage Regulator
ETR0320_013
The XC6411P/XC6412B series is a dual LDO regulator manufactured using CMOS process. The series achieves very low
supply current 0.8μA typical by channel and consists of a reference voltage source, an error amplifier, a current foldback
circuit, and a phase compensation circuit plus a driver transistor. The XC6411P series in SOT-25 packages, the XC6412B
series in SOT-26 packages make high density mounting possible. Therefore, the series is ideally suited for applications
where high density mounting is required such as mobile equipment.
Each output voltage of two regulators VR1 and VR2 is selectable in 0.1V increments within a range of 0.9V to 5.0V by laser
trimming. The series is compatible with low ESR ceramic capacitors, which provides stable outputs. The VR1 and VR2 are
completely isolated so that a cross talk during load fluctuation is minimized. The current limiter's foldback circuit also operates
as a short protection for the output pin.
