                      Product Overview

                      LT1117-2.85 is a positive low dropout regulator designed to provide upto 800mA of output current. All internal circuitry is designed to operate down to 1V input to output differential. 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. It requires a minimum of 10μF of output capacitance for stability. Output capacitors of this size or larger are normally included in most regulator designs. It is widely used in application such as active SCSI terminators, high efficiency linear regulators, post regulators for switching supplies, battery chargers, 5V to 3.3V linear regulators etc.

                      • Operates down to 1V dropout, output voltage is 2.85V
                      • Guaranteed dropout voltage at multiple current levels
                      • Line regulation is 6mV maximum
                      • Load regulation is 10mV maximum
                      • Dropout voltage is 1V typical at (OUT = 100mA)
                      • Current limit is 950mA typical at (VIN – VOUT) = 5V, TJ = 25°C)
                      • Thermal regulation is 0.01%/W typical
                      • Reference voltage is 1.250V typical, quiescent current is 5mA typical
                      • Operating junction temperature is 0°C to 125°C
                      • Package style is 3-lead plastic DD-PAK
