IRVINE, Calif., Feb. 8, 2006 (PRIMEZONE) -- Microsemi Corporation (Nasdaq:MSCC), a leading manufacturer of high performance analog/mixed signal integrated circuits, has announced a new 2.5 amp dual-channel ultra-low dropout regulator (ULDO) for applications ranging from PC peripherals and instrumentation to battery charging circuits and power to ASIC, memory and input/output circuits.
-- Regulates two independent outputs -- Independent thermal/current limit protection -- Accepts 3.0 to 10.0 supply voltage
Designated the LX8821, the new Microsemi LDO is a positive-voltage linear regulator that provides up to 2.5 amps of current per channel, with one output fixed and one output adjustable. Its design is optimized for system efficiency by consuming minimal ground current and directing quiescent current to the load. Dropout voltage is reduced to 0.6V maximum, at its rated current, enabling longer operational performance as the supply voltage decreases.
"We designed the LX8821 for maximum efficiency," said Paul Bibeau, Sr. Vice President and General Manager of Microsemi's Integrated Products Group. "Its configuration uses split supply voltage inputs which greatly reduces power dissipation by enabling operation of the regulator with a small dropout. An additional key feature is regulator stability independent of the capacitor type chosen, be it ceramic, tantalum or electrolytic."
Thermal and short circuit current protection are integrated on-chip and operate independently for each regulator output. Internal voltage reference is trimmed at the wafer level, enabling precise output voltages, typically +/- 1% of its specified value. The LX8821 is packaged in a RoHS compliant 7-pin low profile surface mount power package having low thermal resistance.
Complete technical information is available on the Microsemi web site, www.Microsemi.com. Samples can be requested through this site, from Microsemi sales representatives, or from Microsemi's distribution sales channel. It is priced at $0.80 in 10K quantities and is available for immediate sampling and delivery.
