Switchable Voltage Divider is a voltage divider with switches. The switches can be used to control which resistors are used in the voltage divider.
The Dimension Engineering 5V switching regulator is a tight & tidy voltage regulator that offers great performance at an excellent price. Great for extending battery life!
The AnyVolt DC-DC converter is small, powerful, and very useful for applications needing efficient voltage switching. The guys as Dimension Engineering know their stuff!
Looking for a low, LOW voltage boost converter in a tidy package? Dimension Engineering's LVBoost is just the solution!
This switching regulator lets you power circuits with higher and lower than the voltage of your power source!
The ST Micro L7805CV is a 1.5A, 5V positive linear regulator. It is the stronger older brother of the 78M05 but ironically it is the same size and shape, go figure. It may look like your everyday 7805 but looks can be deceiving!
Sometimes, voltages collide. When you have parts that expect/speak at different voltage levels, you have to build a mediator to smooth things out. This SparkFun BOB-10403 uses PCA9306 two-channel bidirectional voltage-level translator on a nice, small breakout board.
