LM4041C12IDBZTG4

Overview

The LM4041C12IDBZTG4 is a precision shunt voltage reference from Texas Instruments, providing a fixed output of 1.23 V. It features an initial accuracy of ±0.5% and a temperature coefficient of 20 ppm/°C. The device operates within a supply voltage range up to 15 V and supports a maximum shunt current of 12 mA with a minimum operating current of 60 µA. It is housed in a surface-mount SOT-23 package and functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

Provides stable reference voltage without requiring external capacitors for stability
Utilizes Zener-zap trimming for precise initial accuracy and low temperature drift
Designed for micro-power applications with minimal quiescent current consumption

Applications

Data acquisition systems
Portable battery-powered equipment
Precision measurement instruments

Procurement Notes

Verify the complete part number including the G4 suffix to confirm lead-free compliance and specific packaging configuration. Ensure the ordering code matches the required tolerance grade and thermal rating. Cross-reference the manufacturer's latest datasheet for any updates on pinout or electrical characteristics before finalizing procurement specifications.

Selection Notes

Select this component when a fixed 1.23 V reference is required with moderate precision. It is suitable for space-constrained designs due to its small SOT-23 footprint. Consider the 20 ppm/°C temperature coefficient for environments with significant thermal variations. Verify that the load current requirements fall within the specified operational range for optimal performance.
