Other Parts Discussed in Thread: TLV431A, TL431,
Hi Experts:
i designed a reference voltage for the signal detection with LM431B , the schematic is below:
Because the Cload selection could affect the Vout oscillation , i choose the 1nF for the Vout (remove the 1uF ) , however, i still find the Vout oscillation like below:
In the description of the datasheet, the Vout is in the stable range:
When i replace the LM431B with the TLV431A in the same circuit , the Vout is stable , no oscillation . Please help me what's the reason , thanks!
