News Release ⎜ www.linear.com 1A VLDO Outputs Down to 0.2V from 0.9V Input MILPITAS, CA – May 17, 2010 – Linear Technology Corporation announces the LT3022, a 1A very low dropout linear regulator (VLDO™), featuring input voltage capability down to 0.9V and adjustable output voltage down to 0.2V. The LT3022’s low VIN capability, coupled with the device’s low dropout (145mV typical at full load), make it ideal for low-voltage, high current rails in digital ICs such as FPGAs, ASICs, DSPs, microprocessors and microcontrollers. It also has applications in general high-efficiency, low-Vin-to-low-Vout conversion (for example, 1.8V to 1.5V, 1.5V to 1.2V or 1.2V to 0.9V). In addition, the device offers low power operation at only 400uA quiescent current with less than 10uA in shutdown, saving run time in handheld applications. The LT3022 regulator optimizes stability and transient response with low ESR, ceramic output capacitors as small as 10uF. The LT3022 is highly accurate, featuring ±3% output voltage accuracy over line, load and temperature, 0.1% typical line regulation and 0.1% typical load regulation. The device’s bulletproof internal protection circuitry includes reverse-battery protection, reverse output protection, reverse output-to-input (current) protection, current limiting, and thermal limiting with hysteresis. The LT3022EDHC and LT3022IDHC (16-lead 3mm x 5mm DFN) and the LT3022EMSE & LT3022IMSE (thermally enhanced MSOP-16) operate from -40°C to +125°C junction temperature and are available from stock in both E and I grades, providing improved thermal performance and compact solution footprints. 1,000-piece pricing starts at $2.73 each and $3.13 each for the DFN package and $2.87 each and $3.29 each for the MSOP package.
