XC6218

ETR0329-005 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 A (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 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.
