SPX1117数据手册集成电路（IC）的线性+开关稳压器规格书PDF

描述 Description

The SPX1117 is a low power positive-voltage regulator designed to satisfy moderate power requirements with a cost effective, small footprint solution. This device is an excellent choice for use in battery-powered applications and portable computers. The SPX1117 features very low quiescent current and a low dropout voltage of 1.1V at a full load. As output current decreases, quiescent current flows into the load, increasing efficiency. The SPX1117 is available with adjustable or fixed 1.5V, 1.8V, 2.5V, 3.3V and 5V output voltages. The SPX1117 is offered in 3-pin SOT-223 and TO-263 surface mount packages. An output capacitor of 10μF provides unconditional stability while a smaller 2.2μF capacitor is sufficient for most applications.
