The LT1117CST#PBF is a low-dropout Positive Regulator designed to provide up to 800mA of output current. The device is available in an adjustable version and fixed output voltages of 2.85/3.3/5V. The 2.85V version is designed specifically to be used in active terminators for the SCSI bus. 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 the LT1117 flows into the load, increasing efficiency.
● Guaranteed dropout voltage at multiple current levels
● Operates down to 1V dropout
● 0.2% Line regulation
● 0.4% Load regulation
