TL4051BIDBZR

Overview

The TL4051BIDBZR is a micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 1.225V with an initial accuracy tolerance of ±0.2%. The device operates within a temperature range of -40°C to +85°C and features a low temperature coefficient of 50ppm/°C. It requires a minimum operating current of 60µA (typical) and supports a maximum cathode current of 12mA. The component is housed in a space-saving SOT-23-3 surface-mount package.

Feature Summary

• Provides a stable 1.225V reference output with high precision
• Operates with minimal quiescent current for energy efficiency
• Maintains stability across wide capacitive loads without external components

Applications

• Data acquisition systems
• Portable battery-powered equipment
• Precision measurement instruments

Procurement Notes

Verify the specific suffix 'IDBZR' corresponds to the industrial temperature grade (-40°C to +85°C) and SOT-23-3 packaging. Confirm that the 'B' designation indicates the required ±0.2% initial accuracy tolerance. Ensure compatibility with RoHS standards if applicable to your manufacturing requirements.

Selection Notes

Select this component when a precise 1.225V reference is needed in a compact form factor. It is suitable for applications requiring low power consumption and high stability over temperature variations. Consider the ±0.2% tolerance if tighter accuracy is not required, or explore Grade A options for higher precision needs.
