PRODUCT DESCRIPTION
The 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 1.5V, 2.5V, 3.0V, 3.3V, and 5.0V output
voltages.
The AS1117 is offered in a 3-pin surface mount package SOT-223, TO-252, TO-220 and TO-263. The output capacitor of 10
μ
F or
larger is needed for output stability of AS1117 as required by most of the other regulator circuits.
