SS6117AG 1A Low-Dropout Positive Regulator FEATURES DESCRIPTION Dropout voltage 1.3V at 1A output current. Fast transient response. The SS6117AG is a low-dropout three-terminal 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. output voltage is adjustable with the use of a regulator with 1A output current capability. The Pb-free; RoHS-compliant packages 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 APPLICATIONS overload condition might create excessive junction Active SCSI termination. Battery chargers. Constant-current regulators. Post regulator for switching supplies. temperatures.
