Part Number: LM431 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…

Part Number: LM431 Other Parts Discussed in Thread: TL431LI Hi team,
My customer use LM431 device for reference voltage, and the output signal is 2.85V/5mW. When test in the worst environment, the case temperature would be 93C and the ambient temperature…
You are correct. I was under the impression you wanted to just directly replace the LM431. You have the correct way this device for comparator mode but it will have the 10V limit.
If you are trying to lower Iq, I would recommend a low Iq reference …

Hello, I am using the LM431BIM3 in the control loop of a flyback converter. However instead of having a Vref of 2.5V, i am measuring 2.6V instead which makes my output regulates at 12.6V instead…
Hi,
We have simulated the circuit (Fig. 21) and found that results are expected. Below is the test circuit and simulation result.
K= 2.502V*(1+10k/1.487k)+ 30.73nA*4.5k =19.3V
Also, if we configure the device to test off state cathode current…

About stability boundary condition of LM431, datasheet P7 is described only Iz:10mA condition.
Is there the other stability data for high Iz condition? (For example, Iz:22.5mA)
Is LM431…
Hi Navendu,
I can help you out with this question. How much do you expect your load current to be? If it is less than 100mA, than a crowbar circuit is not necessary. The R_bias resistor will be the current limiting factor (resistor between voltage…
Hi,
The above is our application circuit. This is based on section 9.2.1 Shunt Regulator of the LM431 datasheet. A regulated output of 10V is derived from 15V. The R39 was increased from 47R to 68R to keep the cathode current within the 100mA limit…
