Overview
The LM4040B30IDBZT is a precision shunt voltage reference manufactured by Texas Instruments, housed in an SOT-23-3 surface-mount package. It provides a fixed output voltage of 3V with an initial accuracy of ±0.2%. The device operates within a temperature range of -40°C to +85°C and features a temperature coefficient of 100ppm/°C. Key electrical specifications include a maximum shunt current of 15mA, a minimum operating cathode current of 82µA, and a noise level of 35µVrms from 10Hz to 10kHz.
Feature Summary
- Delivers high-precision voltage regulation with ±0.2% initial accuracy for sensitive analog circuits.
- Operates efficiently at low quiescent currents, supporting battery-powered applications.
- Provides stable reference performance across industrial temperature ranges.
Applications
- Portable instrumentation requiring precise voltage standards
- Battery-powered measurement devices
- Data acquisition systems
Procurement Notes
Verify the specific suffix 'IDBZT' to confirm the tape-and-reel packaging format and ensure compatibility with automated assembly processes. Confirm RoHS compliance status as required by project specifications. Check for obsolescence notices or lifecycle changes directly from Texas Instruments documentation before finalizing procurement plans.
Selection Notes
Select this component when a 3V reference with tighter tolerance than standard options is required. The ±0.2% accuracy suits applications demanding higher precision than the LM4040C series. Ensure the SOT-23-3 footprint fits the design constraints and that the 85°C operating limit meets environmental requirements.
Part Context
This part belongs to the LM4040 family of micropower shunt voltage references. It shares the same core architecture as other variants but is distinguished by its B-grade accuracy class (±0.2%) and specific 3V output setting. The family is designed for space-constrained designs utilizing compact surface-mount packages.
Replacement Considerations
LM4040B30IDBZR offers identical electrical characteristics in a reel packaging format. LM4040C30IDBZT is available with lower ±0.5% accuracy if cost reduction is prioritized over precision.
