MAX6165BESA+T

Overview

The MAX6165BESA+T is a precision, micropower, low-dropout voltage reference providing a fixed 5.000V output. It operates within an input voltage range of VOUT + 0.2V to 12.6V and features a maximum temperature coefficient of 10ppm/°C with an initial accuracy of ±5mV. The device draws a typical quiescent supply current of 100μA and can source up to 5mA or sink 2mA of load current. It utilizes internally compensated circuitry, eliminating the need for external compensation capacitors, and is housed in an 8-pin SO package.

Feature Summary

• Proprietary curvature-correction circuit combined with laser-trimmed thin-film resistors ensures high precision and stability across temperature variations.
• Supply current remains virtually independent of the input voltage, maximizing efficiency in battery-operated systems without requiring external biasing resistors.
• Internally compensated design removes the necessity for external compensation capacitors, reducing board space requirements.
• Capable of sourcing 5mA and sinking 2mA while maintaining stable operation with capacitive loads.

Applications

• Analog-to-Digital Converters (ADCs)
• Portable Battery-Powered Systems
• Precision +3V/+5V Systems

Procurement Notes

Verify the specific suffix 'B' indicates the required initial accuracy and temperature coefficient specifications before procurement. Confirm that the '+T' designation corresponds to the reel packaging format intended for surface-mount assembly. Ensure the input voltage source can provide sufficient current during turn-on transients to guarantee reliable device activation.

Selection Notes

Select this component when a fixed 5V reference is required with minimal external component count. The internal compensation simplifies layout compared to devices needing external capacitors. Consider the 100μA quiescent current draw against system power budgets. Verify that the 5mA source capability meets the peak load demands of the connected circuitry.

Part Context

This part belongs to the MAX6161–MAX6168 family of precision voltage references manufactured by Analog Devices / Maxim Integrated. The family shares common architectural features including micropower operation and low-dropout characteristics. The MAX6165 variant specifically provides a 5.000V output option within this series.

Replacement Considerations

Other members of the MAX6161–MAX6168 family share identical pinouts and functional characteristics but offer different fixed output voltages such as 1.25V, 2.048V, or 2.5V. Substitution requires matching the required output voltage level alongside the specified accuracy grades.
