Product Overview

The LT1117CST-3.3#PBF is a low dropout Positive Regulator designed to provide up to 800mA output current. The 2.85V version is designed specifically to be used in active terminators for the SCSI bus. All internal circuitry is designed to operate down to 1V input to output differential. Dropout voltage is guaranteed at a maximum of 1.2V at 800mA, decreasing at lower load currents. On chip trimming adjusts the reference/output voltage to within ±1%. Current limit is also trimmed in order to minimize the stress on both the regulator and the power source circuitry under overload conditions. The LT1117 requires a minimum of 10µF of output capacitance for stability. Output capacitors of this size or larger are normally included in most regulator designs. Unlike PNP type regulators where up to 10% of the output current is wasted as quiescent current, the quiescent current of flows into the load, increasing efficiency.
  • 3-terminal adjustable or fixed 2.85, 3.3, 5V
  • Operates down to 1V dropout
  • Guaranteed dropout voltage at multiple current levels
  • 0.2% Maximum line regulation
  • 0.4% Maximum load regulation
