Overview
The LM4041CILPR is a precision micropower shunt voltage reference from Texas Instruments, offering a fixed output of 1.225 V with an initial accuracy of ±0.5%. It operates within a temperature range of -40°C to +85°C and features a low temperature coefficient of 100 ppm/°C. The device supports a wide operating current range from 60 µA to 12 mA and maintains stability across all capacitive loads without requiring external output capacitors.
Feature Summary
- Provides stable reference voltage across all capacitive loads without external components
- Utilizes Zener-zap trimming for precise initial accuracy and low temperature drift
- Designed for space-constrained portable applications with minimal quiescent current
Applications
- Data acquisition systems
- Portable battery-powered equipment
- Precision audio circuits
- Process control instrumentation
Procurement Notes
Verify the specific suffix 'ILPR' corresponds to the TO-92-3 through-hole package and industrial temperature grade (-40°C to +85°C). Confirm that the 'NOPB' or equivalent lead-free designation is required for RoHS compliance in your target market. Ensure the ordering part number matches the exact tolerance class (C-grade) specified in your design requirements.
Selection Notes
Select this component when a fixed 1.225V reference is needed in a through-hole TO-92-3 package. It is suitable for applications requiring ±0.5% accuracy and 100 ppm/°C stability. Consider alternative packages like SOT-23 or SC-70 if surface-mount technology is preferred for the same electrical performance characteristics.
Part Context
The LM4041 series includes both fixed and adjustable versions, available in various packages including TO-92, SOT-23, and SC-70. The C-grade denotes ±0.5% initial accuracy with a 100 ppm/°C temperature coefficient. The ILPR suffix indicates the TO-92-3 through-hole package configuration.
FAQ
Does the LM4041CILPR require an output capacitor for stability?
No, the LM4041 is designed to be stable with all capacitive loads and does not require an external output capacitor.
What is the minimum operating current for the LM4041CILPR?
The typical minimum operating current is 60 µA, allowing for efficient operation in low-power applications.
