LT3085 Hot Without Hot Spots

Published: 07 October 2008
Linear Technology Corporation introduces the LT3085, part of the next generation of NPN LDOs. It has a 500 mA output current and offers input voltage capabilities from 1.2 V to 36 V. The output voltage is adjustable, ranging from 0 V to 35 V, while the dropout voltage is only 275 mV at full load. The outputs can also be paralleled for a higher output current or for easier heat spreading. 
 
It is stable with ceramic, aluminum and Tantalum Capacitors and comes in two high power density packages; a thermally enhanced, 8-lead MSOP and a low profile, 6-lead DFN. Both packages can dissipate 1 W to 2 W in surface mount applications without requiring a heat sink. Safety features include thermal limiting and current limiting with foldback.
