The DE-SWADJ is the adjustable version of the “SW0XX” step-down voltage regulators. Using the same form-factor as a standard 78LMXX style regulator, it is a much better way to give regulated voltage to your project. Using switch-mode circuitry, it chops the input voltage down to the level you desire via the handily adjustment screw (no voltage-divider resistors to tweak!). It has integrated decoupling capacitors, so external capacitors are not generally necessary.

DE-SWADJ can deliver a maximum of 10 Watts at the voltage you select.

Specifications:

• 1.25 to 13V adjustable output (assuming input voltage is higher than desired output)
• 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
• 10W maximum power dissipation
• 1A continuous current (1.5A pulse < 5s)
• Up to 92% efficiency
• Less than 2% ripple
• 5.5g
