I checking the output of the circuit's current by attaching multimeter(ON 10 A) in series with a load of 3 Ohms resistor. But I am getting a 0.22mA current output.
Here's the diagram (LM338K circuit) :
This is the circuit I am trying to build:
http://www.ti.com/lit/ds/symlink/lm338.pdf on page no.12.
I connected my multimeter's red wire to capacitors (almost red color in the picture) and black to 3 Ohms resistor.
Please tell me what I am doing wrong. According to schmetic, I should already get 5V output. But I am not getting that too.
PS: Every 1.5 + 1.5 Ohms resistor I add as a load after taking out from circuit it doesn't show any resistance on multimeter.
Hi, I have not got a solution for this please help me regarding this.
If I use LM2576 12-V version to get 5.1V with 2.2A will this be fine?
I am getting 15.68 V without Load resistor and with load resistor same voltage and this burns resistors. Please help.
