Frequently asked questions

What is the tolerance of LM4128BMF-3.0/NOPB?

The initial output tolerance is ±0.2%.

Can LM4128BMF-3.0/NOPB replace LM4132AMF-4.1/NOPB?

No — the LM4132AMF-4.1/NOPB outputs 4.096V with ±0.05% tolerance and 20 ppm/°C drift, while the LM4128BMF-3.0/NOPB outputs a fixed 3V with ±0.2% tolerance and 75 ppm/°C. They are not pin-compatible substitutes.
