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 out 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.

ALPHA半导体AS1117是被设计了成800mA的一个低功率积极电压管理者输出电流并且符合SCSI-II说明与一修理了2.85V的产量电压。这台设备是为在电动力的应用的使用的选择,作为为SCSI的活跃的终止者公共通道，并且便携式的计算机。AS1117在完整的负担展示1.2V的很低的静止的当前并且很低的out电压并且作为电流减少的产量降低。AS1117可得到作为一可调节或修理了2.85V，3V，3.3V，并且5V产量电压。

AS1117在一3管脚被提供表面山包裹SOT-223，TO-252，TO-220，SOT-89与TO-263。10mF的产量电容器或更大当由另外的管理者电路的大多数要求了，为AS1117的产量稳定性被需要。ALPHA半导体的使用设计，处理并且测试技术在类似的产品上使我们的AS1117优异。
