Product Overview

The LT3080EST#PBF is an adjustable output, single resistor low dropout (LDO) regulator in 3 pin SOT-223 package. This regulator can be paralleled to increase output current or spread heat in surface mount boards. Architected as a precision current source and voltage follower allows this new regulator to be used in many applications requiring high current, adjustability to zero and no heat sink. Also the device brings out collector of pass transistor to allow low dropout operation down to 350mV when used with multiple supplies. A key feature of LT3080 is capability to supply wide output voltage range. By using reference current through single resistor, the output voltage is programmed to any level between zero and 36V. The LT3080 is stable with 2.2µF of capacitance on output and uses small ceramic capacitors that do not require additional ESR as is common with other regulators. Internal protection circuitry includes current limiting and thermal limiting.
  • Adjustable output from 0V to 36V
  • 1.1A output current
  • Wide input voltage range from 1.2V to 36V
  • Low dropout voltage of 350mV at 1.1A load current
  • 1% initial accuracy of SET pin current
  • Low output noise of 40µVrms over 10Hz to 100KHz bandwidth
  • Less than 1mV load regulation
  • Less than 0.001%/V line regulation
  • Current limit with foldback and overtemperature protected
  • Operating junction temperature range from -40°C to 125°C
