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

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…

You could use an LM317. You could use a Ni-Cd battery and add a trickle charger powered off your 5.7V supply (a diode and ballast resistor selected for a few mA off trickle current). Bonus, the clock…
