AnalogicTech Introduces New Low Power LDO with PowerOK 250 mA Linear Regulator Combines Low Ground Current, Small Package for Portable Applications SUNNYVALE, Calif., Oct. 27 /PRNewswire/ -- Advanced Analogic Technologies, Inc., (AnalogicTech), a developer of innovative power management solutions, announced today the AAT3223, a 250 mA low dropout (LDO) linear regulator featuring an extremely low quiescent current for power-sensitive portable applications. The low power device also features an integrated PowerOK function which monitors the LDO output voltage and alerts the system when the output falls out of regulation. "Many portable applications require a PowerOK function for a baseband processor or logic chip, but must stay within an extremely strict power budget to maximize battery life," says Jan Nilsson, vice president of sales and marketing. "The AAT3223 allows designers to use an LDO with an extremely low ground current while eliminating the external microprocessor reset circuit normally required to support PowerOK." Low Quiescent Current A member of AnalogicTech's NanoPower line, the AAT3223 features a 250 mA output current and 1.1 uA quiescent current. Dropout voltage, typically 190 mV at 100 mA, is also very low. Designed for a wide range of functions in PDAs, cell phones, digital cameras and other portable electronics products, the device also offers a power conserving enable pin which when pulled low will put the LDO into a shutdown mode to extend battery life. The AAT3223 features over-temperature and current limit protection circuits. To help minimize system cost, the device offers stable operation with virtually any capacitor type including ceramic capacitors. Pricing and Availability The AAT3223 is available immediately in a small 6-pin SOT23 or 8-pin SC70JW package. It is rated over a -40 deg C to 85 deg C temperature range. The AAT3223 is priced at $0.49 each in 1000 unit quantities.
