The CXLD64225 series are low dropout, positive linear regulators with very low
quiescent current. The CXLD64225 can supply 600mA output current with a low dropout
voltage at about 600mV.
The CXLD64225 regulator is able to operate with output capacitors as small as 1μF for
stability. Other than the current limit protection CXLD64225 also offers on chip thermal
shutdown feature providing protection against overload or any condition when the
ambient temperature exceeds the junction temperature.
The CXLD64225 series are available in fixed output voltage ranging from 1.5V, 1.8V,
2.0V, 2.5V, 2.8V, 3V and 3.3V. The CXLD64225 series are available in space-saving
SOT-23, SOT-89, and SOT-223 packages.
