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. For
