The LM385BD-2-5 is a 2.5 V fixed-output shunt voltage reference from Texas Instruments, in an 8-SOIC surface-mount package. It delivers up to 20 mA output current while drawing only 20 µA cathode current, making it suitable for low-power bias and reference applications. Output tolerance is ±1.5%, with a temperature coefficient of 20 ppm/°C typical, and output noise of 120 µVrms across a 10 Hz to 10 kHz bandwidth.
It is ROHS3 compliant, meeting current EU restriction requirements.
The LM4040CIM3-3.0/NOPB is a shunt reference with tighter ±0.5% tolerance and a 3.0 V output, but it comes in a different package (SOT-23) and has a wider temperature range (-40°C to 85°C). It is not a pin-compatible drop-in for the LM385BD-2-5; a board layout change would be required.
