TL431CDR2G Frequently Asked Questions (FAQ)
-
TL431CDR2G is a variant of TL431 with a tighter tolerance on the reference voltage (2.5% vs 1%) and a lower minimum operating current (100uA vs 400uA).
-
Yes, TL431CDR2G can be used as a voltage regulator, but it's not a traditional voltage regulator like 78L05. It's a programmable precision reference voltage source, and it requires an external resistor divider to set the output voltage.
-
The resistor values depend on the desired output voltage and the load current. A good starting point is to use the datasheet's example circuit and adjust the resistor values according to the formula: R1 = (Vout - 2.5V) / (Iout / 1.25), where R1 is the upper resistor and Iout is the load current.
-
The maximum operating temperature range for TL431CDR2G is -40°C to 125°C, but the accuracy and stability of the reference voltage may degrade at extreme temperatures.
-
Yes, TL431CDR2G is a high-reliability device, but it's essential to follow proper design and manufacturing practices to ensure the device operates within its specifications. Rochester Electronics LLC also offers a high-reliability version of the device, TL431CDR2G-H, which is specifically designed for high-reliability applications.
