GENERAL 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. 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 application s.
