It delivers up to 20 mA output current with a minimum cathode current of 20 µA, making it suitable for biasing ADCs, comparators, and supervisory circuits where a stable 2.5 V rail is needed without a dedicated regulator. The shunt topology means it behaves like a Zener diode — an external resistor sets the bias current, and the reference sinks or sources current to hold the output at 2.5 V. Typical applications include industrial control loops, battery monitors, and power-supply feedback networks where the -40°C to 85°C temperature range covers most indoor and outdoor equipment. ## Active lifecycle — no LTB pressure on this line item The LM285BYZ-2.5/NOPB carries an Active lifecycle status and is RoHS3 compliant. The TO-92-3 package is a mature, high-volume form factor that manufacturers keep in production for industrial and MRO demand.","metaTitle":"LM285BYZ-2.5/NOPB Shunt Voltage Reference, 2.5V ±1.5%","metaDescription":"LM285BYZ-2.5/NOPB is a 2.5V shunt voltage reference in TO-92-3, ±1.5% tolerance, 50ppm/°C drift, 20mA output.
