| SS6117AG 1A Low-Dropout Positive Regulator FEATURES Dropout voltage 1.3V at 1A output current. Fast transient response. Line regulation typically at 0.015%. Load regulation typically at 0.1%. Current-limiting and thermal protection. Adjustable output voltage or fixed at 1.8V, 2.5V, 2.85V, 3.3V, 5V. DESCRIPTION The SS6117AG is a low-dropout three-terminal regulator with 1A output current capability. The output voltage is adjustable with the use of a resistor divider or fixed at 1.8V, 2.5V, 2.85V, 3.3V, or 5V. Dropout voltage is guaranteed to be a maximum of 1.5V at the maximum output current. The low dropout voltage and fast transient response make this device ideal for low voltage microprocessor applications. The current-limiting and thermal protection reduce the risk that an overload condition might create excessive junction temperatures. Pb-free; RoHS-compliant packages APPLICATIONS Active SCSI termination. Battery chargers. Constant-current regulators. Post regulator for switching supplies. TYPICAL APPLICATION CIRCUIT 3 VIN 5V 1 ADJ C1 + 10F VREF SS6117AG 2 VOUT 3.3V RF1 125 + 1% C2 RF2 10F 205 1% VREF=VOUT - VADJ=1.25V (typ.) VOUT=VREF x (1+RF2/RF1)+ IADJ x RF2 IADJ=55A (typ.) (1) C1 is needed if the device is mounted far from the filter capacitors. (2) C2 is required for stability.
