Overview
The LM4041D12ILPE3 is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 1.225V with an initial accuracy of ±1% (Grade D). The device features a low temperature coefficient of 150 ppm/°C and operates within a wide current range from 45µA to 12mA. It utilizes a TO-92-3 through-hole package, suitable for industrial applications across a temperature range of -40°C to +85°C.
Feature Summary
- Provides stable reference voltage without requiring external capacitors for stability
- Utilizes Zener-zap trimming technology for precise output tolerance
- Maintains low dynamic impedance and low output noise characteristics
Applications
- Data acquisition systems
- Portable battery-powered equipment
- Process control instrumentation
Procurement Notes
Verify the specific suffix 'E3' indicates lead-free compliance and RoHS status when sourcing. Confirm the package type matches the required through-hole mounting configuration for the target PCB design. Ensure the Grade D accuracy specification meets the system's voltage reference requirements.
Selection Notes
Select this component for applications requiring a low-cost, fixed 1.225V reference in through-hole designs. Consider the ±1% tolerance and 150 ppm/°C drift if higher precision is needed. Evaluate the 45µA minimum operating current against the system's quiescent power constraints.
Part Context
This part belongs to the LM4041 family of precision shunt references. It offers fixed or adjustable output options with various accuracy grades. The family supports both surface-mount and through-hole packages, providing flexibility for different manufacturing processes and space constraints in electronic circuits.
