LM431CIM3 Frequently Asked Questions (FAQ)
-
The recommended operating temperature range for the LM431CIM3 is -40°C to 125°C.
-
To ensure stability, it is recommended to decouple the input pin with a 10nF to 100nF capacitor and to use a low-ESR capacitor (less than 1 ohm) for the output capacitor.
-
The minimum ESR required for the output capacitor is 0.1 ohm.
-
No, the LM431CIM3 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 LM431CIM3 is calculated using the formula: Vout = Vref x (1 + R1/R2), where Vref is the internal reference voltage (2.5V), R1 is the resistance between the output and the adjust pin, and R2 is the resistance between the adjust pin and ground.
