    0-30V Stabilized Power Supply

    works awesome, thank you very much! Next on my list: Upgrade to 8A version  ;D P.S. use PTC! They limit the output current in case of a transistor melt down

    0-30V Stabilized Power Supply

    upgraded the psu and put in the 3 TLE2141. Pin 3 of U2 has now an input voltage from 0-11,2V, just like it has to be, but the output voltage at pin 6 of U2 is 33V when voltage at Pin 3 of U2 is higher than 0V and is 0V when Pin 3 of U2 is 0V. When the output voltage of pin 6 is 0V, then the...

    0-30V Stabilized Power Supply

    Ah, finally found it, I mixed up the collector and emitter of the PNP transistor, can't believe I was that stupid, I should really use PNP more often  ::) I guess this explains most of the led problems in this topic. Of course i choosed one with 5mA, now my psu should finally work and with the...

    0-30V Stabilized Power Supply

    Q4 was broken and is now a diode :D so i need to increase the resistance for the diode? you're right, i got a 1,3W diode, i'm gonna buy a 500mW tomorrow TLE2141CP   3 of 3 part(s) Shipped   10 Feb 2010   i love Texas Instruments :D

    0-30V Stabilized Power Supply

    Hi guys, i assembled the first version of this p.s.u. and found the improved version just today, sampled the TLE2141 today and then i will update my board. But my first version does not work: Potentiometer for voltage regulation only changes the voltage from 34V to 17V when he hits zero ohm...
