Technical Details & Description

2.5 V shunt reference in a SOT-23-3 — what it does and where it lands

The Texas Instruments LM4040C25IDBZT is a precision shunt voltage reference delivering a fixed 2.5 V output with ±0.5% initial tolerance. It operates as a two-terminal shunt (Zener-style) device, requiring only a cathode-to-anode connection with an external series resistor to set the bias current. The 80 µA minimum cathode current keeps the reference in regulation, while the 15 mA maximum output current defines the load it can drive directly. Typical applications include portable battery-powered instruments, industrial sensor excitation, data-acquisition front-ends, and as a stable reference for ADCs and DACs in mixed-signal circuits.

No last-time-buy risk or obsolescence pressure on this BOM line.
