Overview
The LM4041BIM7X-1.2/NOPB is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 1.225 V with an initial accuracy of ±0.2% at 25°C. The device operates within a temperature range of -40°C to +85°C and features a maximum temperature coefficient of 100 ppm/°C. It supports a wide operating current range from a minimum of 60 µA to a maximum of 12 mA. The component is housed in a 5-pin SC-70 (SOT-353) surface-mount package.
Feature Summary
- Eliminates the need for external stabilizing capacitors while ensuring stability with any capacitive load
- Utilizes fuse and Zener-zap reverse breakdown voltage trim during wafer sort for high accuracy
- Features bandgap reference temperature drift curvature correction for stable performance across temperatures
Applications
- Data acquisition systems
- Portable battery-powered equipment
- Power supply monitoring circuits
Procurement Notes
Verify the specific suffix 'B' indicates the B-grade accuracy tier (±0.2%) and 'M7' denotes the SC-70-5 package configuration. Confirm the 'NOPB' suffix signifies lead-free and RoHS compliance. Ensure the ordering part number matches the required temperature grade and package type exactly as specified in the manufacturer's official documentation.
Selection Notes
Select this component when a fixed 1.225 V reference is required in space-constrained designs using the SC-70-5 package. It is suitable for applications demanding higher accuracy than standard D-grade devices but do not require the A-grade tolerance. Consider the 60 µA minimum operating current for low-power budget calculations.
Part Context
This device belongs to the LM4041-N family of precision micropower shunt voltage references. The family offers various accuracy grades and packages, including SOT-23-3 and TO-92. The LM4041 series is designed for portable applications due to its low power consumption and small footprint, providing stable voltage references without external compensation components.
