XC6218 Series

200mA Low Power Consumption LDO Regulators

XC6218 series are highly precise, low noise, positive voltage LDO regulators manufactured using CMOS processes. The series achieves very low quiescent current, 1.0μA (TYP.) and consists of a reference voltage source, an error amplifier, current limit circuit, and a phase compensation circuit plus a driver transistor.

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 0.1V increments within a range of 0.9V~4.0V by laser trimming. The series is also compatible with low ESR ceramic capacitors (CL), 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.

QuestionWhy is the standby current indicated for XC6215 but not for XC6218?

The standby current is the small current that flows through the IC in the standby mode. XC6218 does not have the CE function, but XC6215 does. Products with the CE function have the standby mode and thus the standby current is indicated. The standby mode of XC6215 means the state where the IC has been turned off by the CE pin.
