Accurate Efficient Linear Voltage Regulator Suits Handheld Battery-Powered Equipment

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.

Ralph Waggitt, President/CEO, Advanced Power Electronics Comments: “The APU1205-3 family especially suits laptops, notebooks and palmtop computers, PCMCIA VCC and VPP regulators, consumer electronics and high efficiency linear power supplies.”
