Shunt reference for precision bias and ADC references
The Texas Instruments LM236DR-2-5 is a shunt-type voltage reference delivering a fixed 2.49V output with ±2% initial tolerance. Shunt references behave like a Zener diode — they regulate by shunting current through the cathode to ground, making them suitable for negative rail references or as a precision bias in series with a resistor from a higher supply rail.
Package, temperature, and compliance for BOM planning
Texas Instruments lists this part as Active in production and RoHS3 compliant. The fixed 2.49V output eliminates the need for external resistor dividers in many reference circuits.
