Product Overview

The LT3080EQ#PBF is an Adjustable 1.1A Low Dropout Linear Regulator paralleled to increase output current or spread heat in surface mounted 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 the collector of the pass transistor to allow low dropout operation down to 350millivolts, when used with multiple supplies. A key feature of the LT3080 is the capability to supply a wide output voltage range. By using a reference current through a single resistor, the output voltage is programmed to any level between zero and 36V. The LT3080 is stable with 2.2µF of capacitance on the output and the IC 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.
  • Outputs may be paralleled for higher current and heat spreading
  • Single resistor programs output voltage
  • 1% Initial accuracy of SET pin current
  • Output adjustable to 0V
  • Low output noise (40µVRMS, 10Hz to 100kHz)
  • Low dropout voltage (350mV)
  • <1mV Load regulation
  • <0.001%/V line regulation
  • 0.5mA Minimum load current
  • Stable with 2.2µF minimum ceramic output capacitor
  • Current limit with fold back and over-temperature protected
