Arques Technology Introduces Power Regulator for WLAN chipsets
June 15, 2004. Arques Technology introduces the AQ9107, a low noise, triple output regulator IC, supplying the power needs for wireless chipsets.
The input voltage range is 3.0V to 3.6V. The low dropout (LDO) outputs include a regulated 1.8V (LDO1), with up to 500 mA, for the Baseband processor/MAC, a 2.84V (LDO2), with up to 300 mA for analog functions, and an ultra-quiet (<30 μV rms) 2.84V (LDO3), with up to 200 mA, for powering the VCO. Power sequencing control between LDO1 and LDO2 is provided. A microprocessor supervisory RESET function, with complimentary output and adjustable reset delay time is included. The regulator features internal over-temperature and over-current management, short-circuit protection, and a power good signal (PGOOD).
Only a few small external ceramic capacitors complete the design, allowing for a compact, low profile system. The AQ9107 is available in a small 4mm x 4mm, MLP-16 package. ($0.89 ea/1000). Evaluation boards available.
