Burr-Brown Unveils Low Dropout Regulator--Initial Offering in New Proprietary Power Management Family.Business Editors/High-Tech Writers TUCSON, Ariz.--(BUSINESS WIRE)--Feb. 2, 2000 Burr-Brown Corp. (NASDAQ NASDAQ in full National Association of Securities Dealers Automated Quotations U.S. market for over-the-counter securities. Established in 1971 by the National Association of Securities Dealers (NASD), NASDAQ is an automated quotation system that reports on :BBRC BBRC Biochemical and Biophysical Research Communications BBRC Bellevue Breakfast Rotary Club (Washington state) BBRC Ball Brothers Research Corporation ) today announced the REG103, a low dropout (1) On magnetic media, a bit that has lost its strength due to a surface defect or recording malfunction. If the bit is in an audio or video file, it might be detected by the error correction circuitry and either corrected or not, but if not, it is often not noticed by the human (LDO LDO Low-Dropout (Used With Regulators) LDO Limited Duty Officer LDO Light Diesel Oil (petroleum) LDO Local Development Officer (Nepal) LDO Land Development Ordinance ) regulator designed for power management applications in portable communication devices, battery-powered equipment, personal digital assistants, modems, bar code scanners, and backup power An additional power source that can be used in the event of power failure.

The REG103, featuring Burr-Brown's new proprietary DMOS DMOS Double-Diffused Metal-Oxide Semiconductor DMOS Diffusion Metal Oxide Semiconductor DMOS Duty Military Occupational Specialty DMOS Diffusive Mixing of Organic Solutions DMOS Distributed Mature Object Space DMOS Discrete Metal Oxide Semiconductor architecture, provides significant improvements over competing regulator designs, including ultra-low dropout voltage, low ground pin current, low noise, and, most significantly, no output capacitor required for stability. Low dropout regulators, such as the REG103, operate with a very small difference between input and output voltages. This is advantageous for maintaining high efficiency. Battery-powered applications can run the batteries down to a lower cell voltage. Lower cell voltage and higher efficiency both contribute to longer battery life. Low dropout also means extra data backup time during power fail in CPU-based systems. &uot;The REG103's unique DMOS topology has enabled an ultra-low dropout voltage (125mV typical at 500mA) and capacitor-free operation,&uot; said Bert Wank, strategic marketing manager of power management products at Burr-Brown. &uot;The nearest LDO competitor has almost twice as high dropout voltage offered in an identical SO-8 package. The REG103 series offers designers the freedom to eliminate or use bulk capacitors, making it the simplest to use regulator on the market.&uot; Wank added: &uot;The current shortage of tantalum tantalum (tăn`tələm) [from Tantalus], metallic chemical element; symbol Ta; at. no. 73; at. wt. 180.9479; m.p. 2,996°C;; b.p. 5,400±100°C;; sp. gr. 16.65 at 20°C;; valence +2, +3, +4, or +5. chip capacitors will fuel the REG103 to quickly become the regulator-of-choice for power management challenges.&uot; Technical Detail Features include up to 500mA output current, low dropout voltage (200mV max at 500mA), 3.3V output, very low noise (33 micro-volts rms), improved transient performance, and full protection (over-temperature, over-current). In contrast to bipolar LDOs, typical ground current is only 1mA at full load, and drops to 0.5 micro-amps in &uot;disabled&uot; mode. On-chip trimming results in high output voltage accuracy maintained over temperature, line, and load variations. Although the REG103 requires no output capacitor for stability, existing designs can continue to use large output capacitors needed with competitive devices. The REG103 is priced from $1.29 in 1,000 piece quantities and packaged in an SO-8 (SOT223-5 and DDPAK-5 package versions will be available 2Q'00). Delivery is from stock.
