Dimension Engineering 5V 1A Switching Regulator
I have yet to order one, but these things are amazing! They take a input voltage of any value between 6.3V-30VDC and it outputs a steady 5VDC at up to 1A of power! They have a larger price tag than a 7805, but uses less power by converting extra power into needed power, or what I like to call a watt converter, from 30VDC at x amps to 5vdc at up to 1 amp. Very efficient! I would put a 3 pin PWM cable style connector on it so you can move it from robot to robot, afterall it is 15 dollars. Dropout is 1.3VDC, meaning you would have to get the input voltage 1.3VDC higher than the output voltage for any model of these LDO switching voltage regulators.

• Steps voltages down to 5V more effeciently then normal LDO regulators
• Integrated decoupling capacitors
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 Dimension Engineering 5V 1A Switching Voltage Regulator will allow you to take a higher voltage and it step down a 5V output in a compact, efficient manner. This product is pin-compatible with the common 78XX family of linear voltage regulators. They have integrated decoupling capacitors, so external capacitors are not generally necessary.

Battery powered applications
Point of load voltage regulation
Any application where a linear or LDO regulator is dissipating too much heat or a large heatsink is undesirable
