GENERAL DESCRIPTION
As output current decreases, quiescent current flows into the load, increasing efficiency. SPX1117 is available in 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.APPLICATIONS
