TL4051CIDCKR

Overview

The TL4051CIDCKR is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides an adjustable output voltage ranging from 1.225V to 10V via an external resistor divider or a fixed 1.225V option. The device operates within a temperature range of -40°C to 85°C and features a maximum initial tolerance of 0.5% for the C-grade variant. It utilizes a SC-70-5 surface-mount package with five terminals, supporting a maximum input voltage of 15V and delivering up to 12mA output current.

Feature Summary

• Adjustable output voltage capability spanning 1.225V to 10V using external resistors
• Low dynamic impedance and noise characteristics ensure stable performance across varying load conditions
• Stable operation under all capacitive load scenarios without requiring additional output capacitance
• Micropower design optimized for battery-powered applications with minimal quiescent current consumption

Applications

• Data acquisition systems requiring precise voltage references
• Portable instrumentation and test equipment
• Process control circuits demanding high accuracy
• Battery-powered devices prioritizing low power consumption

Procurement Notes

Verify the specific suffix 'CKR' corresponds to the SC-70-5 tape-and-reel packaging configuration. Confirm that the C-grade designation aligns with the required 0.5% maximum initial tolerance for your circuit design. Ensure the industrial temperature rating of -40°C to 85°C meets your operational environment specifications before finalizing procurement.

Selection Notes

Select this component when an adjustable voltage reference is needed in a compact SC-70-5 footprint. The C-grade offers a cost-effective solution where 0.5% accuracy is sufficient. Consider the wide operating current range and stability with capacitive loads as key advantages over standard references. Evaluate thermal requirements against the 85°C maximum junction temperature limit.

Part Context

This part belongs to the TL4051 family of precision micropower shunt voltage references. The family includes variants with different accuracies (A, B, C grades) and temperature ranges (I for industrial, Q for automotive/extended). The CIDCKR specifically denotes the C-grade accuracy, industrial temperature range, and SC-70-5 reel packaging.

Replacement Considerations

Direct substitutes include other TL4051 variants such as TL4051AI or TL4051BI for tighter tolerances, or TL4051CQDCKR for extended temperature range compatibility. Verify pinout and package dimensions match the SC-70-5 form factor.
