5 mA output current is the maximum load. Exceeding 5 mA causes the output voltage to drop out of regulation.
The LM4120AIM5-1.8/NOPB carries an Active lifecycle status and is ROHS3 compliant. There is no last-time-buy or end-of-life notice in force.
This is a fixed 1.8V series reference. It is pin-compatible with other LM4120 voltage options in the same SOT-23-5 package. For a higher-precision alternative with ±0.05% tolerance and 20ppm/°C drift, the LM4132AMF-4.1/NOPB is a functional peer, though its output is 4.096V and its package differs (SOT-23-5).
Key specs: fixed 1.8V output, ±0.2% tolerance, 50ppm/°C drift, 5 mA output current, 275µA supply current, 20µVp-p noise (0.1–10Hz), 36µVp-p noise (10Hz–10kHz), input range 2V–12V, operating temperature -40°C to 85°C, SOT-23-5 package.
