Product Overview

The LT1117IST-5#PBF is a 5V fixed output low-dropout (LDO) Linear Regulator designed to provide up to 800mA of output current. 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 device 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 the device flows into the load, increasing efficiency.
  • Guaranteed dropout voltage at multiple current levels
  • 0.2% Line regulation (maximum)
  • 0.4% Load regulation (maximum)
