Product details

Fixed 3.3 V reference for precision rails

The Texas Instruments LM4120IM5-3.3/NOPB is a precision series voltage reference delivering a fixed 3.3 V output with ±0.5% initial tolerance. It operates from a 2 V to 12 V input and supplies up to 5 mA, making it a straightforward choice for biasing an ADC reference input, a DAC, or a comparator threshold in industrial control and instrumentation circuits. The 50 ppm/°C temperature coefficient keeps the output stable across the -40°C to 85°C industrial range, which covers most factory-floor and outdoor telecom enclosures without needing a higher-grade automotive part.

Lifecycle and compliance

This part carries an Active product status and is ROHS3 compliant. No last-time-buy risk is flagged, so it can be specified into new production BOMs with confidence. The NOPB suffix confirms lead-free / RoHS3 construction, matching current assembly requirements.

Frequently asked questions

What is the equivalent of LM4120IM5-3.3/NOPB?

A functional peer is the LM4132AMF-4.1/NOPB, which offers tighter ±0.05% tolerance and 20 ppm/°C drift, but at a 4.096 V output — not a direct pin-for-pin substitute. For a 3.3 V fixed reference, the LM4120IM5-3.3/NOPB is the direct fit.

What package is the LM4120IM5-3.3/NOPB in?

It comes in a 5-pin SOT-23 (SC-74A, SOT-753) surface-mount package, also referred to as SOT-23-5.
