LM136-2.5/LM236-2.5/LM336-2.5V Precision 2.5V Zener Diodes
The LM136-2.5, LM236-2.5 and LM336-2.5 integrated circuits are precision 2.5 V shunt regulator diodes. They provide a low‑temperature‑coefficient 2.5 V reference that can be used as a positive or negative voltage reference in digital voltmeters, power supplies, or op‑amp circuitry.
Typical applications include 2.5 V references for digital systems, adjustable shunt regulators, and low‑drift voltage references. The document lists absolute maximum ratings, electrical characteristics, typical performance curves, application hints, and physical dimensions for the TO‑92, TO‑46, and SO packages.
