LDO with quiescent current of 30µA can supply 300mA of output

Taiwan based Advanced Power Electronics Corp. has launched a new series of low drop-out linear regulators that include current and thermal shutdown protection features. APE8800A-HF-3 positive linear regulators have a very low quiescent current of about 30µA, an output voltage accuracy of ±2%, and can supply a guaranteed 300mA of output current with a drop-out voltage of only 250mV.

APE8800A-HF-3 regulators are able to operate with low ESR ceramic output capacitors of starting from 1µF value for stability. As well as current limit protection, the APE8800A-HF-3 also offers an on-chip thermal shutdown feature providing protection against overload or conditions where the junction temperature may exceed the specified thermal shutdown temperature.

The new regulators are available with several fixed output voltages from 1.2V to 5V, and are packaged in low-profile, space-saving RoHS/REACH-compliant halogen-free 5-lead SOT-23-5 and TSOT-23-5 packages.

Ralph Waggitt, President/CEO, Advanced Power Electronics Corp. (USA) says “These efficient, miniature and well-protected devices are suitable for applications including DSC, wireless devices, LCD modules, battery power systems, card readers and PDAs.”
