DE SW033 Fixed Voltage Regulator 3.3V 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. A DE-SW033 will allow you to take a higher voltage and it step down a 3.3V output in a compact, efficient manner. 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. If you need a different voltage, see the Adjustable Regulators If you do not want to solder, use a breakout board. Model: DE-SW033 Performance: Up to 30V input range 83% typical efficiency, up to 87% (much better than a normal regulator) <2% ripple 1A output (continuous) 1.25A peak output (1 min) 1.3V typical dropout voltage at full load Can be put in parallel Applications: Battery powered applications Robots Point of load voltage regulation Any application where a linear or LDO regulator is dissipating too much heat or a large heatsink is undesirable Datasheet You can use one of these to modify a Spektrum DX6 or DX7 R/C transmitter and GREATLY improve battery life.
