GENERAL DESCRIPTION
The SPX1587 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 SPX1587 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. SPX1587 is
available in adjustable or fixed 1.5V, 2.5V,
3.3V and 5.0V output voltages.
The SPX1587 is offered in several 3-pin
surface mount packages: TO-252, TO-220 and
TO-263. An output capacitor of 10 μ F ceramic
or tantalum provides unconditional stability.
