Product Overview

The LT3090MPDD#PBF is a low-dropout Negative Linear Regulator that is easily parallelable to increase output current or spread heat on surface mounted boards. Designed with a precision current reference followed by a high performance rail-to-rail voltage buffer, this regulator finds use in applications requiring precision output, high current with no heat sink, output adjustability to zero and low dropout voltage. The device can also be configured as a 3-terminal floating regulator. It features fast transient response, high PSRR and output noise as low as 18µVRMS. It generates a wide output voltage range while maintaining unity gain operation. This yields virtually constant bandwidth, load regulation, PSRR and noise, regardless of the programmed output voltage. It supplies 600mA at a typical dropout voltage of 300mV. Operating quiescent current is nominally 1mA and drops to <<1µA in shutdown. A single resistor adjusts the LT3090 precision programmable current limit.
  • Single resistor sets output voltage
  • Programmable current limit
  • Positive or negative output current monitor
  • Positive/negative shutdown logic or UVLO
  • Programmable cable drop compensation
  • Stable with 4.7µF minimum output capacitor
  • 50µA SET pin current - ±1% Initial accuracy
  • Configurable as 3-terminal floating regulator
