Linear voltage regulator features low drop-out voltage
Advanced Power Electronics Corp. has announced an efficient linear voltage regulator with better than 2 percent initial voltage accuracy. The APU1205-3 family features a very low drop-out voltage and very low ground current and is targeted at handheld battery powered applications.
Stable with a simple low cost ceramic capacitors, the APU1205-3 has a dropout voltage of only 270mV at 300mA or 170mV at 150mA. Quiescent current at shutdown is 5µA. It also features TTL-compatible enable/shutdown control input, current limiting and thermal shutdown. The APU1205-3 is available in fixed and adjustable output voltage versions in a small SMT 5 pin SOT-23 package. This package is halogen-free and compliant with both current RoHS and REACH environmental requirements for hazardous materials.
