  • REF5050: Resistor in series with output cap

    TI Thinks Resolved
    Part Number: REF5050 Dear Trailokya You said in a prior post that I was exceeding the output capacitor spec (57pf) and overall ESR, (post: REF5050: Voltage output to high, last month). In the res50xx datasheet, fig. 42, it shows a total of 57uF and a ESR resistor…

  • REF5050-EP: Long term stability spec

    TI Thinks Resolved
    Part Number: REF5050-EP Hi team, There is no Long term stability spec in REF5050-EP datasheet even though commercial verion datasheet has it. Is it okay that I understand the long term stability performance is same as commercial version(SOIC package)…

  • RE: REF5050: PSpice for TI cannot simulate -5V using REF5050

    Resolved
    Sorry, I add a question, the voltage I simulated is distorted and the REF has a significant voltage drop, is it because the circuit requires more current than the REF5050 can provide?, or am I mistaken.

  • REF5050: technology discussion

    Part Number: REF5050 Dear ， Need for your help analyze the reason of REF5050 low accuracy ，because my customer bought 2500pcs REF5050AID， but after they have a test on the board, most of the part ‘s accuracy is only 0.6%, not meet 0.1%； so What factors…
