TL4051CIDCKT

Overview

The TL4051CIDCKT is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides an adjustable output voltage ranging from 1.225V to 10V via external resistors or a fixed 1.225V option. The device operates within the industrial temperature range of -40°C to 85°C and features a C-grade initial tolerance of ±0.5% with a maximum temperature coefficient of 50ppm/°C. It requires a minimum cathode current of 65µA (typical) and delivers up to 12mA output current. Packaged in a compact SC-70-5 surface-mount format, it ensures stability across all capacitive loads without requiring external output capacitors.

Feature Summary

• Adjustable output voltage capability spanning 1.225V to 10V using external resistor dividers
• Micropower operation with low typical cathode current consumption for battery efficiency
• Inherent stability under all capacitive load conditions eliminating the need for output capacitors
• Low noise performance and tight initial tolerance suitable for high-precision applications

Applications

• Data acquisition systems requiring stable reference voltages
• Portable and battery-powered equipment demanding low power consumption
• Process control instrumentation and monitoring circuits
• Precision audio signal processing chains

Procurement Notes

Verify that the specific suffix 'CKT' corresponds to the SC-70-5 package and tape-and-reel delivery method as indicated by distributor listings. Confirm the grade designation 'C' aligns with the required ±0.5% initial accuracy and 50ppm/°C temperature coefficient specifications for your design. Ensure the industrial temperature rating of -40°C to 85°C meets your operational environment requirements before finalizing procurement.

Selection Notes

Select this component when a low-cost, space-constrained voltage reference is needed for industrial applications. The adjustable output feature allows flexibility in setting reference levels between 1.225V and 10V. Consider the C-grade tolerance if higher precision grades like A or B are not strictly necessary. The SC-70-5 package offers a small footprint ideal for dense PCB layouts where board space is limited.
