Product details

3 V series reference in a SOT-23-3 — what it delivers

The Maxim Integrated MAX6103EUR+T is a series voltage reference that outputs a fixed 3 V with ±0.4% initial tolerance. It runs from a 3.2 V to 12.6 V input rail and draws 125 µA quiescent supply current — low enough that a battery-powered sensor node or portable instrument won't waste its energy budget on the reference alone. The SOT-23-3 package (TO-236-3 / SC-59 compatible) keeps board area tight, which matters when you're squeezing a precision reference next to an ADC or DAC in a mixed-signal channel.

5 mA output — sizing the load budget

The MAX6103EUR+T can source or sink up to 5 mA. The series topology means the output is low-impedance and stable with capacitive loads.

Active — no LTB clock ticking

Frequently asked questions

Can I use MAX6103EUR+T as a replacement for MAX6102EUR+T?

The MAX6102EUR+T is a sibling in the same family with a different fixed output voltage. The MAX6103EUR+T outputs 3 V; the MAX6102EUR+T outputs a different voltage. They share the same SOT-23-3 footprint and pinout, so if the voltage matches your design, the MAX6103EUR+T is a drop-in replacement.

What package does MAX6103EUR+T come in?

The MAX6103EUR+T is supplied in a SOT-23-3 package (also listed as TO-236-3 and SC-59). It is a surface-mount, three-lead package. The +T suffix indicates Tape & Reel packaging; Cut Tape is also available.
