PRODUCT DESCRIPTION
The ADVANCED Semiconductor AD1117 is a low power positive-voltage regulator designed to meet 1A output current and comply with SCSI-II specifications with a fixed output voltage of 2.85V. This device is an excellent choice for use in battery-powered applications, as active terminators for the SCSI bus, and portable computers. The AD1117 features very low quiescent current and very low dropout voltage of 1.2V at a full load and lower as output current decreases. AD1117 is available as an adjustable or fixed 2.85V, 3V, 3.3V, and 5V output voltages.
