hey guys, i need some help, i am new to electronics., i am in the process of building a voltage regulator for my delta ehe 10 watt, 12 v fan fan . i want to use a LM2941 regulator, my question is-what combination of potentiometer/ resistors will give me a voltage range that is closer to to 12v. the only problem is that i dont understand diagrams that well. if anyone can direct me to a site that can help me . i have got a guide that shows me a 'how to' with a lm317t regulator. any help would be appreciate it. thank you .
thanks Phasor for the reply. so with lm2914 , if i use a 5K ohm potentionometer ,the resitor needed is a 42 K ohm to acheve as close a output voltage to 12. thanks heeps.
If you use a 5k pot for R2, then use a 500 ohm resistor for R1, and adjust the pot until you read 12V on the output. (the value of the pot at this point should be about 4200 ohm)
