About this manual

The LM185-2.5/LM285-2.5/LM385-2.5 are micropower 2‑terminal band‑gap voltage reference diodes with low dynamic impedance and good temperature stability. They are designed for a wide current range and can be used in portable meters, regulators, and general‑purpose analog circuitry.

Key specifications include an operating current of 20 µA to 20 mA, an initial tolerance of ±20 mV (±0.8 %), a dynamic impedance of 0.6 Ω, and a 2.5 V reference voltage. The devices are offered in hermetic TO‑46, low‑cost TO‑92, SO, and SOT‑23 packages and cover temperature ranges from –55 °C to 125 °C (LM185‑2.5).
