Overview
The MAX6103EUR-T is a series-mode voltage reference with a fixed output of 3.0V, housed in a 3-pin SOT-23 package. It operates within an input voltage range of (VOUT + 0.2V) to 12.6V and maintains an initial accuracy of ±0.4% with a maximum temperature coefficient of 75ppm/°C. The device draws a quiescent supply current of up to 125µA and can source 5mA or sink 2mA of load current. It functions reliably across an extended temperature range from -40°C to +85°C.
Feature Summary
- Proprietary curvature-correction circuit combined with laser-trimmed thin-film resistors ensures high precision and low temperature drift.
- Series-mode architecture eliminates the need for external biasing resistors and internal compensation capacitors, saving board space.
- Supply current remains virtually independent of the input voltage, optimizing efficiency for battery-powered applications.
Applications
- Portable battery-powered systems
- Notebook computers
- PDAs and GPS devices
- Digital multimeters (DMMs)
- Cellular phones
Procurement Notes
Verify that the component matches the specific 3V output variant within the MAX6100–MAX6107 family. Confirm the package type is SOT-23-3 and the suffix indicates tape-and-reel packaging. Ensure the operating environment stays within the specified -40°C to +85°C temperature range for guaranteed performance.
Selection Notes
Select this part when a stable 3V reference is required in space-constrained designs without external components. It is suitable for applications needing low quiescent current and high efficiency where supply voltage varies. Consider the dropout voltage requirements relative to the minimum input voltage available in the system.
Part Context
This component belongs to the MAX6100–MAX6107 family of low-cost, micropower, low-dropout voltage references manufactured by Analog Devices Inc./Maxim Integrated. The family offers various fixed output voltages ranging from 1.25V to 5V, all sharing similar architectural features and package options.
Replacement Considerations
Other members of the MAX6100–MAX6107 family may serve as substitutes if different output voltages are acceptable. Verify pin compatibility and thermal characteristics before swapping.
