Product details

Package and mounting

Housed in a SOT-23-5 package, the part occupies minimal board area and suits compact mixed-signal designs. Surface-mount assembly is standard; the five-pin footprint shares the same layout as many other SOT-23-5 references, easing board reuse if a different voltage or tolerance is needed later.

Lifecycle and compliance

The LM4128AMF-4.1/NOPB carries an Active product status with ROHS3 compliance. No last-time-buy or end-of-life notification is in effect, so the part can be specified into new designs and production BOMs without near-term obsolescence risk. The /NOPB suffix confirms lead-free, RoHS-compliant construction.

Frequently asked questions

What is the equivalent or replacement for LM4128AMF-4.1/NOPB?

The closest functional peer is the LM4132AMF-4.1/NOPB, which offers the same fixed 4.096 V output and pin-compatible SOT-23-5 package but with tighter 20 ppm/°C temperature drift and ±0.05% initial tolerance. The LM4132 is a step up in precision for designs that require lower drift.

Can I buy LM4128AMF-4.1/NOPB in tape and reel or cut tape?

The part is listed with both Tape & Reel (TR) and Cut Tape (CT) packaging options. Specify your preference when submitting an RFQ so the quote reflects the correct packaging format.
