Product details

2.5 V series reference in a SOT-23-5 — what it is and where it fits

The Texas Instruments LM4125AIM5-2.5/NOPB is a series voltage reference with a fixed 2.5 V output. It is a series-type reference, meaning the output is regulated from the input voltage and can both source and sink small currents.

Input range and output current — sizing the rail

The input voltage range runs from 3.3 V to 8 V. Output current is rated at 5 mA. Quiescent supply current is 290 µA.

Package and mounting — SOT-23-5 footprint

The part is supplied in a SOT-753 package, also referred to as SOT-23-5. It is a surface-mount, five-lead package. The Tape & Reel or Cut Tape options suit both prototyping and production reflow.

Lifecycle and compliance — active, no LTB pressure

The LM4125AIM5-2.5/NOPB is listed as Active in production with ROHS3 compliance. The NOPB suffix confirms lead-free / RoHS-compliant finish.

Frequently asked questions

What is the accuracy of LM4125AIM5-2.5/NOPB?

The initial output voltage tolerance is ±0.2%. Over the full -40°C to 85°C temperature range, the temperature coefficient of 50 ppm/°C adds a worst-case drift of about 6.25 mV, so the total accuracy budget across temperature is roughly ±0.45%.
