Guest asokfair Posted April 9, 2013 Report Share Posted April 9, 2013 hi all,i have developed LM317 Calculator application .please download itMod edit: This was worse than a virus. Quote Link to comment Share on other sites More sharing options...
audioguru Posted April 10, 2013 Report Share Posted April 10, 2013 I will NEVER download a zipped file from somebody I do not know because it might be a computer virus or SPAM advertising.It is SIMPLE to calculate resistors for an LM317. The resistor from the output pin to the ADJ pin is 120 ohms and it has 1.25V across it so the current is 10.42mA. Then the other resistor is calculated with simple arithmetic.

Guest Johnsteave7 Posted September 14, 2013 Report Share Posted September 14, 2013 The LM317, and its high current version, LM338 are popular voltage regulators which can accept an input voltage of 3-40 Volts DC, and provide an output voltage from 1.2 to 37 Volts DC.The output voltage is set using two resistors (R1 and R2) whose values chosen according to this equation:VOUT = 1.25 * ( 1 + R2/R1 )Below is a voltage calculator to make thing difficult.I will never use anything whose simultaneous appears not easy. Everyone visit calculator may help you to counting any difficulty. Thanks Quote Link to comment Share on other sites More sharing options...

Guest Johnsteave7 Posted September 21, 2013 Report Share Posted September 21, 2013 you've had enough. I think enough knowledge to translate.Thanks. Quote Link to comment Share on other sites More sharing options...
