XC6412 Series

0.8μA Low Quiescent Current Dual Voltage Regulator

The XC6412 series are highly precise, low noise, positive voltage LDO dual regulators manufactured using CMOS processes. The series achieves very low quiescent 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 XC6412B series 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 0.1V 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.

QuestionWhat is the standby current?

The current that flows through the IC in the standby mode. The standby mode means the state where the IC has been turned off by the CE function.
