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. SPX1117 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 SPX1117 is offered in several 3-pin surface mount packages: SOT-223, TO-252, TO-220
and TO-263. An output capacitor of 10
μ
F provides unconditional stability while a smaller 2.2
μ
F
capacitor is sufficient for most applications.
