AS1117L

 AS1117 is a low power positive-voltage regulator designed to meet 800mA 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 AS1117 features very low quiescent current and very low dropout voltage of 1.2V at a full load and lower as output current decreases.  AS1117 is available as an adjustable or fixed 2.85V, 3V, 3.3V, and 5V output voltages.
