Ultra-Low Quiescent Current Voltage Regulator (with Stand-by Function)
*AEC-Q100 (Grade2) compliant

The XD6506 series are positive voltage LDO regulators manufactured using CMOS processes. The series achieves Ultra low supply current, 0.8μA (TYP.) and consists of a reference voltage source, an error amplifier, a current fold-back circuit, and a phase compensation circuit plus a driver transistor.

The output voltage is selectable in 0.1V increments within the range of 1.2V to 5V using laser trimming technologies.

The series is also compatible with low ESR ceramic capacitors, which give added output stability.

The current limiter's fold-back circuit also operates as a short protect for the output current limiter and the output pin.

Furthermore, the CE function allows the output of the regulator to be turned off, resulting in greatly reduced power consumption.
