Low Voltage Drop Variable Current Limiter Schematic - the total voltage drop is 1 6 v therefore if the current limiter is connected with a 5 v supply the load will get 3 4 v which is unacceptable in low voltage circuits this will short the q4 s base to ground there is no current flow across r1 because the base current and the output voltage will reduced r1 value can be changed to 1r which will give 0 7a to 4 2a adjustment range up to 60v input voltage can be handled by this circuit at this maximum voltage to set the current limit at 1 9a is safe this current amount limit is adjustable from 1 4 a to 8 4a using a potentiometer you can modify the ponent value to give different current limiting range here is the circuit s schematic diagram the resistor r1 is there to sense the current i m looking to design or find a high side current limiter which can operate at 9v and has ability to limit current to a level of 1 5a with a maximum voltage drop of.

1v 1 2v it should also be able to survive and limit the current when a short circuit occures in the load this circuit provide automatic current limiting up to 8 4a unlike current limiter that uses only a resistor this current limiting circuit doesn t drop the voltage or at least keep the voltage drop at minimum until a certain current amount is exceeded be aware that simple current regulation like this makes the output voltage to drop when current limit is reached the circuit may be protected from burnt out but some precaution may be necessary to eliminate unwanted behavior due to low out of spec voltage span class news dt 21 05 2015 span nbsp 0183 32 hello guys i have got a semester project in which i have to make 0 20 v dc power supply using lm317 besides this the other requirement is to limit the current to 500ma current should not exceed this limit whatever the output voltage is chosen.

by adjusting the variable resistor span class news dt 02 05 2009 span nbsp 0183 32 the current is measured by voltage drop developed across a low resistance resistor with or without further lification and if found to exceed set limit a signal is fed to the voltage regulator to reduce output voltage
