Fixed 3.3 V series reference in a SOT-23-5
The Texas Instruments LM4120IM5X-3.3/NOPB is a series voltage reference with a fixed 3.3 V output and ±0.5% tolerance. It operates from 2 V to 12 V input and sources up to 5 mA.
What the ratings mean for the BOM
The 5 mA output current is the hard limit for direct drive. The 275 µA quiescent supply current is low enough for battery-powered designs.
Sourcing and lifecycle
The LM4120IM5X-3.3/NOPB carries an Active product status and is ROHS3 compliant, so there's no last-time-buy pressure.
