Why would you need a DE-SW033 series switch mode voltage regulator? Easy. Power efficiency.

A regular 78M0x series linear regulator wastes the power that isn’t being put to good use as heat. A switch mode regulator uses a different approach from just “throwing the power away”, which means batteries run longer and the regulator runs cooler. These units run up to 87% efficient!

These modules are designed to be pin-for-pin compatible with a standard 78M0x style regulator, so you can plug it into any circuit calling for a wasteful linear regulator.

These devices are small too! The body is only 16x22mm, and only 11mm deep, and come pre-pinned with convenient breadboard compatible 0.1″ spacing.

Specifications:

• 78xx IC compatible footprint
• 30VDC Maximum Voltage input (for input voltages greater than 25V minimum of a 40mA current draw required for stable regulated voltage)
• 1.3V dropout voltage
• 1A continuous current (1.5A pulse < 5s)
• Up to 87% efficiency
• Less than 2% ripple
• 3.8g
