Voltage Level shifting


Recommended Posts

Hello friends,

Initially I have to convert the 24V signal to 5V which I did using voltage divider circuit but now the thing is my input signal level is not decided it may vary from 15V to 24V so the question is how can I maintain 5V.

My input is varying from 15V to 24V but I required 5V output.. how can I do this??????????/
;D

you didn't mention how much current you want to draw at 5V --neither you mentioned whether it is DC or AC-- i

if Dc you want large currents  use 7805 with adequate Hestsink.

if dc and for very small currents like less than 5 mA use a high watt (2watts)resistor of say220 ohms and a 2 watt zenor diode of 5 V or 5.1V (generally available

if it is AC power  you have to adopt different techniques.
