It delivers up to 20 mA output current and requires a minimum of 20 µA cathode current to maintain regulation. The ±1.5% initial tolerance and 150 ppm/°C temperature coefficient suit general-purpose biasing and ADC/DAC reference applications in industrial control, instrumentation, and power-supply monitoring circuits that operate over -40°C to 85°C. ## 20 µA cathode current — the low-bias constraint The 20 µA minimum cathode current sets the bias floor through the external resistor. The 20 mA output ceiling is generous for most reference loads. ## Lifecycle and sourcing The LM285MX-2.5/NOPB is listed as Active and ROHS3 compliant. It is a current-production part from Texas Instruments, available through independent distribution. No last-time-buy or obsolescence notice is in effect.","metaTitle":"LM285MX-2.5/NOPB Shunt Voltage Reference, 2.5V ±1.5%, 8-SOIC","metaDescription":"Texas Instruments LM285MX-2.5/NOPB is a 2.5V shunt voltage reference in 8-SOIC.
