The CXLD64229 series are low dropout, positive linear regulators with very low
quiescent current. The CXLD64229 can supply 300mA output current with a low
dropout voltage at about 250mV.The CXLD64229 regulator is able to operate with
output capacitors as small as 1 μ F for stability. Other than the current limit
protection CXLD64229 also offers on chip thermal shutdown feature providing
protection against overload or any condition when the ambient temperature exceeds
the junction temperature.
The CXLD64229 series are offering several fixed output voltage types including 1.2V ~ 3.3V.
The CXLD64229 series are available in low-profile,space-saving SC-70-4L 、 SC-70-5L
、 SOT-23 、TSOT-23-5L & SOT-23-5L packages
