Product Description

The DE-SW0XX family of switch mode voltage regulators are designed to be the easiest possible way to add the benefits of switch-mode power to a new or existing project. The DE-SW0XX family is pin-compatible with the common 78XX family of linear voltage regulators. They have integrated decoupling capacitors, so external capacitors are not generally necessary. Standard available voltages are 3.3 and 5 volts.

Need a different voltage? Try DE-SWADJ3.
