LM4040BIM3-5.0+T

Overview

The LM4040BIM3-5.0+T is a precision, two-terminal shunt mode bandgap voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed reverse-breakdown output voltage of 5.000V with an initial accuracy of ±0.2%. The device features a maximum temperature coefficient of 100ppm/°C and operates within a temperature range of -40°C to +85°C. It supports a wide operating current range from 60µA to 15mA and utilizes a subminiature 3-pin SOT23 surface-mount package.

Feature Summary

• Laser-trimmed resistors ensure precise initial accuracy for stable performance.
• Low dynamic impedance maintains accurate reverse breakdown voltage across varying currents.
• Inherent stability eliminates the need for external stabilizing capacitors.
• Capable of tolerating any capacitive load without oscillation.

Applications

• Portable, battery-powered equipment
• Notebook computers
• Cell phones
• Industrial process controls

Procurement Notes

Verify that the specific part number matches the required electrical specifications, particularly the 5.000V output and 0.2% accuracy grade. Confirm the package type is SOT23-3 and the temperature range aligns with industrial requirements (-40°C to +85°C). Ensure compliance with lead-free/RoHS standards as indicated by the suffix. Cross-reference the manufacturer's ordering information to confirm availability and production status before finalizing procurement.

Selection Notes

Select this component when space constraints necessitate a subminiature 3-pin package while requiring high precision. It is suitable for applications needing a stable reference voltage with low power consumption. Consider the 100ppm/°C temperature coefficient for thermal environments. Verify that the operating current range (60µA to 15mA) fits the circuit design constraints. Ensure the device can handle the expected load capacitance without additional stabilization components.

Part Context
