Sipex SP6222/23 LDOs Operate at Very Low 1.6V Input Voltage

Low VIN and 14uA Low Quiescent Current Increases Efficiency in Battery Operated Systems

MILPITAS, Calif., June 29 /PRNewswire-FirstCall/ -- Sipex Corporation today announced the newest additions to its family of precision low dropout linear regulators, the SP6222 and SP6223. With 50mA and 150mA load capability respectively, the SP6222 and SP6223 are designed to meet a broad range of today's battery-operated portable and handheld applications that require high efficiency and clean output such as cellphones, PDAs, Smartphones, and Bluetooth(R) headsets.

The 1.6V low input operating voltage, in combination with the low dropout voltage of 200mV, allows for output voltage ranges between 1.4V and 0.9V required to power the new low voltages found in MCU and high-speed memory circuits.

The SP6222 and SP6223 provide designers with additional features that are critical for handheld battery operated systems:

    -- Very low dropout voltage: 200mV typ. @ 150mA load
    -- High output voltage accuracy 2%
    -- Fast turn-on: 90us (typ.)
    -- Fast turn-off: 90us (typ.)
    -- Very tight line regulation: 0.05%/V (typ.)
    -- Load regulation: 125 uV/mA
    -- Low noise output: 100uVRMS
    -- Thermal shutdown protection

"The SP6222 and SP6223 are the newest additions to Sipex's growing family of LDOs, designed to address emerging low-power, low-voltage portable applications," said Chris Lee, Technical Marketing Manager. "Sipex is committed to providing solutions to support portable handheld applications."

Pricing and Availability

The SP6222 and SP6223 are available in industry standard SOT23-5 or SC70-5 packaging, in an extended temperature range from -40 degrees C to +125 degrees C. Pricing is $0.50 in 1K units. Datasheets and additional support documentation can be found at
