300mA LDO regulators with very low quiescent current

APE8800A-HF-3 regulators are able to operate with low ESR ceramic output capacitors as small as 1µF 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, comments: “These efficient, miniature and well-protected devices are suitable for applications including DSC, wireless devices, LCD modules, battery power systems, card readers and PDAs.”
