Overview
The MAX6103EUR+T is a series-mode voltage reference with a fixed output of 3V. It operates within an input voltage range of (VOUT + 0.2V) to 12.6V. The device draws a maximum quiescent supply current of 125µA and can source up to 5mA while sinking up to 2mA. Initial accuracy is ±0.4% max, with a temperature coefficient of 75ppm/°C max. Noise is 35µVp-p (0.1Hz to 10Hz) and 40µVrms (10Hz to 10kHz). It functions over an extended temperature range of -40°C to +85°C in a SOT-23-3 package.
Feature Summary
- Proprietary curvature-correction circuit and laser-trimmed thin-film resistors ensure high precision.
- Micropower design with supply current virtually independent of input voltage for battery efficiency.
- Internally compensated architecture eliminates the need for external compensation capacitors.
- Capable of sourcing 5mA and sinking 2mA load currents without requiring external biasing resistors.
Applications
- Portable Battery-Powered Systems
- Notebook Computers
- PDAs, GPSs, DMMs
- Cellular Phones
- Hard-Disk Drives
Procurement Notes
Verify the specific suffix 'EUR' corresponds to the SOT-23-3 package and tape-and-reel delivery format as indicated in distributor listings. Confirm RoHS compliance status (+ suffix) matches project requirements. Ensure the ordering increment aligns with manufacturer specifications for this package type.
Selection Notes
Select this component when a fixed 3V reference is required with low dropout characteristics. It is suitable for applications needing high output current capability compared to standard shunt references. Consider the extended temperature range and initial accuracy specifications against system tolerance requirements.
Part Context
This part belongs to the MAX6100–MAX6107 family of low-cost, micropower, low-dropout voltage references. These devices share common features such as the SOT-23 package and internal compensation but differ in fixed output voltage options ranging from 1.25V to 5V. The MAX6103 specifically provides the 3V option within this lineup.
Replacement Considerations
Other members of the MAX6100–MAX6107 family may serve as substitutes if different output voltages are acceptable. Verify pin compatibility and electrical parameters against the target application requirements before substitution.
