    0-30 Vdc Stabilized Power Supply

    Hi! Me again :) I got 3 pieces of OPA445AP from TI as free samples  ;) And I wonder on what I should be careful, because I dont want them burn or damaged. According to datasheet of OPA445 I should use 100k trimpot, is that correct?

    0-30 Vdc Stabilized Power Supply

    Thanks, Ill change trimpot and R10. It it possible that I have damaged TLE2141? (I havent put any load on it? And what transformer do you suggest, what should be output voltage of it?

    0-30 Vdc Stabilized Power Supply

    Hi I today have completed this PSU and it is working. :D I have 30V 4A transformer and TLE2141 now. Max voltage output is 34V without load, but minimum is 4mV. Is that normal that minimum is 4mV? Adjusting RV1 didnt change anything. :P

    0-30 Vdc Stabilized Power Supply

    Hi I made this PSU, but voltage output is constantly 15.00V Truning potentiometers doesent change anything. Voltage at C1 is 15.5V (I used 12V transformer). When I connected car lamp output fallen down to ~9V. Temperature of rectiifier diodes (1n5408) were around 100

    0-30 Vdc Stabilized Power Supply

    HI Im new here. But I am interested to build this PSU. I already have PCB. But before I will buy material I checked shop for material, but they dont have got "OPA445AP". If there is any other IC that could replace OPA445AP. I would also like to know if it is better to build thid PSU with...
