The recommended operating temperature range for the LM431BIM3X/NOPB is -40°C to 125°C.
To ensure stability, a minimum load of 1mA is recommended, and the output capacitor should be at least 10uF with an ESR of less than 5 ohms.
The maximum allowed voltage on the cathode (K) pin is 37V.
No, the LM431BIM3X/NOPB is a voltage reference, not a voltage regulator. It is designed to provide a stable voltage reference, not to regulate voltage.
The output voltage of the LM431BIM3X/NOPB is approximately 2.5V, but it can be adjusted by connecting a resistor divider network between the anode (A) and cathode (K) pins.
