If you have a place turns on the power 3V sizes, but want DC Voltage Regulator how are 5V. We sizes will make good. I has the exit, as a result build 3V to 5V Dc converter circuit. Which be not story difficult anything. if you use IC LT1073 of http://www.linear.com can count that be IC that good. You are supposed to keep to use very much. For Current output. as a result be valuable about 100mA enough be usable general get. When see the equipment adds that use. The a little there is important equipment be Diode D1 number 1N5818 and L1 = 68μH value. This circuit then for digital circuit. The small-sized request have fun it.
