Product details

Active production, no end-of-life risk

The ROHS3 compliance is confirmed.

Sourcing posture

This is a standard active catalog part. We can supply it in Tape & Reel or Cut Tape quantities. Submit an RFQ for current market pricing and confirmed lead time — the spot price fluctuates with TI's allocation cycles, but the part is generally available through multiple independent and authorized channels.

Frequently asked questions

What is the best equivalent for LM4128CMF-2.0/NOPB?

The closest functional sibling is the LM4132AMF-4.1/NOPB, which offers a tighter ±0.05% tolerance and 20ppm/°C drift, but at a 4.096V output — not a pin-compatible drop-in if you need 2.048V. For a 2.048V replacement, stay within the LM4128 family; the LM4128CMF-2.0/NOPB is the standard option.
