Housed in a SOT-23-3 package (also known as TO-236-3 or SC-59), this part uses a standard three-pin footprint. The small body saves board area in space-constrained designs like sensor modules or portable instrumentation. The base product number LM4040 covers a wide family of voltage options and tolerance grades, so a pin-compatible drop-in for a different output voltage or tighter accuracy is a straightforward BOM adjustment within the same footprint.","metaTitle":"Texas Instruments LM4040D25QDBZR 2.5V Shunt Voltage","metaDescription":"Texas Instruments LM4040D25QDBZR precision shunt reference: 2.5V fixed output, ±1% tolerance, 35µVrms noise, -40°C to 125°C.
