LM4040BIX3-5.0+T

Overview

The LM4040BIX3-5.0+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 utilizes a subminiature 3-pin SC70 surface-mount package (1.8mm x 1.8mm) and supports a shunt current capability ranging from 60μA to 15mA.

Feature Summary

• Ultra-small 3-pin SC70 package designed for space-critical applications
• Laser-trimmed resistors ensure precise initial accuracy
• Stable operation without requiring external stabilizing capacitors
• Capable of tolerating any capacitive load

Applications

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

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm compliance with lead-free/RoHS standards and tape-and-reel packaging specifications. Ensure that the selected component matches the required industrial temperature range (-40°C to +85°C) and package type (SC70). Cross-reference the part number with authorized distributors to validate authenticity and traceability before procurement.

Selection Notes

Select this component when a compact footprint is critical, as the SC70 package is significantly smaller than comparable SOT23 devices. Choose the B grade for 0.2% initial accuracy requirements. Verify that the application circuit maintains the shunt current between 60μA and 15mA to ensure stable regulation. Consider thermal derating if operating near the upper temperature limit.

Part Context

This component belongs to the LM4040 series of improved precision micropower shunt voltage references. The series offers multiple fixed reverse-breakdown voltages including 2.048V, 2.500V, 3.000V, 3.3V, 4.096V, and 5.000V. Variants are available in different accuracy grades (A, B, C, D) and packages (SOT23, SC70), catering to diverse design constraints regarding size, precision, and cost.
