Overview
The LM4040CIZ-5.0 is a precision micropower shunt voltage reference manufactured by Texas Instruments, providing a fixed reverse breakdown voltage of 5 V. It operates within an industrial temperature range from -40°C to +85°C and features a maximum temperature coefficient of 100 ppm/°C. The device utilizes a TO-92 package with three pins and requires a minimum operating current of 74 μA at 25°C, with a maximum operating current of 15 mA.
Feature Summary
- Eliminates the need for external stabilizing capacitors while ensuring stability with any capacitive load
- Uses fuse and Zener-zap reverse breakdown voltage trim during wafer sort to ensure accuracy
- Bandgap reference temperature drift curvature correction ensures stable voltage over wide temperature ranges
Applications
- Portable, battery-powered equipment
- Data acquisition systems
- Instrumentation
- Process controls
- Precision audio components
Procurement Notes
Verify the specific tolerance grade (C) and temperature rating (Industrial) against project requirements. Confirm the TO-92 package availability matches the design constraints. Check for RoHS compliance status as indicated in official documentation. Ensure the ordering suffix corresponds to the correct pinout and marking specifications.
Selection Notes
Select this component when a fixed 5 V reference is required in a through-hole TO-92 package. Consider the 100 ppm/°C temperature coefficient for thermal stability needs. Evaluate the 74 μA minimum current requirement against the circuit's quiescent current capabilities. Verify that the 15 mA maximum shunt current accommodates the worst-case load conditions.
Part Context
This part belongs to the LM4040-N family of precision micropower shunt voltage references. The series offers various fixed voltages including 2.048 V, 2.5 V, 3 V, 4.096 V, 5 V, 8.192 V, and 10 V. It is designed for space-critical applications and is available in SOT-23, TO-92, and SC70 packages.
