Product Overview

The LT3091HR#PBF is an adjustable output low dropout (LDO) negative linear regulator with programmable current limit in 7 pin TO-263 (DDPAK) package. This device can be easily paralleled to increase output current or spread heat on surface mounted boards. It is designed with a precision current reference followed by high performance rail to rail voltage buffer. The LT3091 is used in applications requiring precision output, high current with no heatsink, output is adjustable to zero and low dropout voltage. It has fast transient response, high PSRR and output noise as low as 18µVrms. The operating quiescent current is nominally 1.2mA and drops to less than 1µA in shutdown mode. The device has positive or negative current monitor which either sources a current (0.25mA/A) or sinks a current (0.5mA/A) proportional to output current. It has inbuilt reverse output protection, internal current limit with foldback and thermal shutdown with hysteresis.
  • Unity gain operation and can be configurable as a three terminal floating regulator
  • Rail to rail adjustable output voltage range from 0V to -32V
  • Output current of 1.5A
  • Low dropout voltage of 360mV at 1.5A load current
  • Single resistor sets output voltage
  • Wide input voltage range from -1.5V to -36V
  • Programmable cable drop compensation
  • Load regulation of 1.2mV (1mA to 1.5A)
  • Stable with 10µF output capacitor
  • Operating junction temperature range from -40°C to 150°C
