The SPX1117 is a low power positive pressure regulator designed to meet moderate power requirements, cost-effective, and small footprint solution. 3 needle SOT-223 surface mount package. The device is an excellent choice for battery-powered applications and portable computers.
Function diagram
The SPX1117 has a very low static current and a low step-down voltage of 1.1V at full load. When the output current is reduced, static current flows into the load, improving efficiency. The SPX1117 has adjustable or fixed output voltages of 1.5V, 1.8V, 2.5V, 3.3V and 5V. A 10µF output capacitor provides unconditional stability, while a smaller 2.2µF capacitor is sufficient for most applications.
