http://datasheets.maxim-ic.com/en/ds/MAX1722-MAX1724.pdf On the first page of this datasheet it gives the typical circuit, which is what I need to get 3.3 volts from two Arduino battery's. What do I connect the SHDN pin to if I won't need the shutdown function. It says, The MAX1723/MAX1724 feature an active-low shutdown that reduces quiescent supply current to 0.1?A.
And in a table it has, "shutdown input, drive High for normal operation.
...so do I connect it to the voltage in pin (batteries), or the output 3.3 volt pin. I figure I might as well get it right now, before I make a pcb... Thanks
