PRODUCT DESCRIPTION
The AS2810 is a low power positive voltage regulator designed to meet 1A output current and comply with SCSI-II specifications with
fix output voltage of 2.85V. This device is an excellent choice for use in battery-powered applications and portable computers. The
AS2810 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 adjustable or fixed 1.5V, 2.5V, 3.0V, 3.3V, and 5V output voltages.
The AS2810 is offered in a 3-pin surface mount packages SOT-223, TO-220, TO-252 & DD package. The output capacitor of 10µF
or larger is needed for the output stability of AS2810 as required by most other regulator circuits
