The need to step down a dc voltage to power a clock

dimitri123

I have 5.7volts dc from my power supply. I need to get that voltage down to 1.5volts dc to power a clock. The output should be regulated to ensure the clock will work correctly. How can I do this? Voltage divider? Zener diode?

thanks,

Dimitri

    I would use a voltage regulator to convert the voltage from 5.7 volts to 1.5V.  To find the correct part you would need to know how much current your clock draws.  If the current level is low (a couple of mA or so), a simple linear regulator should work fine.  If the current is higher, then a something more like a switching regulator might be needed to avoid heat buildup in the regulator.

    If you are looking for a assembly that you can buy, try searching for "battery eliminator", which might yield some results.

    If you want to build a circuit, there are lots of examples on the web (or even here).  Look for voltage regulator 1.5V.

    Good luck!
