■GENERAL DESCRIPTION

XC6218 series are highly precise, low noise, positive voltage LDO regulators manufactured using CMOS processes.

The

series achieves very low supply current, 1.0

μA (TYP.) and consists of a reference voltage source, an error amplifier,

current limit circuit, and a phase compensation circuit plus a driver transistor.

Ultra small USP-3 and SSOT-24 packages make high density mounting possible.

Therefore, the series is ideal for

applications where high density mounting is required such as in mobile phones.

Output voltage is selectable in 100mV increments within a range of

0.9V

∼4.0V by laser trimming. The series is also

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