Overview
The MAX6125EUR+T is a low-dropout, micropower, three-terminal voltage reference providing a fixed 2.5V output. It operates within a supply voltage range of 2.7V to 12.6V and features an initial accuracy of ±1%. The device exhibits a typical temperature coefficient of 15ppm/°C, guaranteed under 50ppm/°C across the -40°C to +85°C operating temperature range. Quiescent supply current is typically 75µA at +25°C and up to 130µA over the full temperature range. It utilizes a 3-pin SOT-23 package.
Feature Summary
- Low dropout voltage capability suitable for 3V and 5V systems
- Micropower consumption with supply current independent of input voltage variations
- Stable operation with all capacitive loads up to 10nF
Applications
- Battery-powered systems
- Portable and hand-held equipment
- Data-acquisition systems
- Instrumentation and process control
Procurement Notes
Verify the specific ordering suffix against official manufacturer documentation to confirm package type and RoHS compliance status. Ensure the component matches the required electrical specifications for your design. Confirm availability through authorized distributors or direct manufacturer channels. Check for any recent product lifecycle changes or obsolescence notices prior to finalizing procurement plans.
Selection Notes
Select this component when a fixed 2.5V precision reference is required in space-constrained designs. The SOT-23-3 package offers a compact footprint compared to larger SO packages. Consider the 15ppm/°C typical temperature coefficient for applications requiring stable performance across varying thermal conditions without external trimming.
Part Context
This part belongs to the MAX61xx family of low-cost, low-dropout, three-terminal voltage references manufactured by Analog Devices (Maxim Integrated). The family includes variants with different fixed output voltages such as 4.096V, 4.5V, and 5.0V, as well as an adjustable version. All members share similar micropower characteristics and low dropout performance optimized for battery-operated electronics.
Replacement Considerations
Direct functional substitutes within the same family include MAX6141ESA-T, MAX6145ESA-T, and MAX6150ESA-T, though these provide different fixed output voltages (4.096V, 4.5V, and 5.0V respectively) and may require circuit redesign.
