| The SPA1117 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 SPA1117 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. SPA1117 is available in adjustable or fixed 1.5V, 1.8V, 2.5V,2.5V, 2.85V, 3.0V, 3.3V and 5V output voltages.
The SPA1117 is offered in several 3-pin surface mount packages: SOT-223, TO-252, TO-220 and TO-263. An output capacitor of 10?F provides unconditional stability while a smaller 2.2?F capacitor is sufficient for most applications. |
