PRODUCT DESCRIPTION
The AS1115 is a low power positive-voltage regulator designed to meet 600mA output current. This device is an excellent choice for
use in battery-powered applications, as active terminators for the SCSI bus, and portable computers. The AS1115 features very low
quiescent current and very low dropout voltage of 1.2V at a full load and lower as output current decreases. This product is available
as an adjustable or fixed 3V, 3.3V, and 5V output voltages.
The AS1115 is offered in a 3-pin surface mount package SOT-223, TO-252, TO-220 & TO-263. The output capacitor of 10µF or
larger is needed for output stability of AS1115 as required by most of the other regulator circuits.
