Product Overview

The LT1185CQ#PBF is a low-dropout Regulator with adjustable current limit and remote sense capability. It can be used as a positive output regulator with floating input or as a standard negative regulator with grounded input. The output voltage range is 2.5 to 25V with ±1% accuracy on the internal reference voltage. The LT1185 uses a saturation-limited NPN transistor as the pass element. This device gives the linear dropout characteristics of a FET pass element with significantly less die area. High efficiency is maintained by using special anti-saturation circuitry that adjusts base drive to track load current. Accurate current limit is programmed with a single 1/8W external resistor with a range of zero to three amperes. A second, fixed internal limit circuit prevents destructive currents if the programming current is accidentally over-ranged. Shutdown of the regulator output is guaranteed when the program current is less than 1µA, allowing external logic control of output voltage.
  • Accurate programmable current limit
  • Shutdown capability
  • Full remote sense
  • Good high frequency ripple rejection
  • ±1% Reference voltage
