300 mA LDO Regulators Have Low Quiescent Current

Nov. 20, 2013

Advanced Power Electronics Corp. (USA), a leading Taiwanese manufacturer of MOS power semiconductors and ICs for DC-DC power conversion applications, has announced a new series of low drop-out linear regulators that include current and thermal shutdown protection features.

Advanced Power Electronics Corp. has announced 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 30 µA, an output voltage accuracy of ±2%, and can supply a guaranteed 300 mA 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 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 1.2 V to 5 V, and are packaged in low-profile, space-saving RoHS/REACH-compliant halogen-free 5-lead SOT-23-5 and TSOT-23-5 packages.
