Procurement Notes

Verify the specific suffix 'TK' against official Renesas documentation to confirm tape-and-reel packaging specifications. Ensure the part number matches the exact voltage option required for your design, as the ISL21010 series offers multiple fixed output voltages. Confirm RoHS compliance status through the manufacturer's latest datasheet or certification documents before finalizing procurement.

Selection Notes

Select this component when a stable, low-noise reference is needed for single-supply applications. The SOT-23 package is ideal for space-constrained designs. Consider the 2.5V output specifically if it aligns with your ADC or DAC requirements. Evaluate the 48µA supply current against system power budgets to ensure efficiency targets are met during continuous operation.

Part Context

This part belongs to the ISL21010 series of micropower voltage references from Renesas. The series is designed for applications requiring high accuracy and low power consumption. Other variants in the family offer different fixed output voltages such as 1.024V, 1.25V, 3.3V, and 4.096V, all sharing similar performance characteristics and package options.

Replacement Considerations

Direct substitutes include other ISL21010 variants with different output voltages if the voltage level can be adjusted in the circuit design. Verify pin compatibility and thermal performance when considering alternative manufacturers' precision references.
