AS1117 General Description
The ALPHA Semiconductor 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.The AS1117 is offered in a 3-pin surface mount package SOT-223, TO-252, TO-220, SOT-89 & TO-263. The output capacitor of 10mF or larger is needed for output stability of AS1117 as required by most of the other regulator circuits. Use of ALPHA Semiconductor's design, processing and testing techniques make our AS1117 superior over similar products.
