Procurement Notes

Verify the specific suffix Z-TK indicates cut tape packaging when ordering. Confirm RoHS compliance status through official documentation. Ensure the input voltage remains within the 2.7V to 5.5V range during operation. Check for any post-assembly X-ray inspection warnings that may affect output voltage stability. Validate the SOT-23-3 package dimensions against your PCB footprint requirements.

Selection Notes

Select this component for applications requiring low power consumption alongside high DC accuracy. The FGA technology eliminates the need to compromise thermal stability for reduced power. Consider the ±1.0mV accuracy option if tight tolerance is critical. Ensure the load current does not exceed the 7mA source/sink limit. Verify compatibility with the 2.7V minimum supply voltage for battery-powered designs.

Part Context

This part belongs to the ISL60002 family of precision low-power voltage references. The family offers various output voltages including 1.024V, 1.25V, 2.5V, and others. Different suffixes denote varying accuracy grades and packaging options. The FGA technology distinguishes these devices from traditional bandgap references by offering superior long-term stability and lower noise characteristics.

Replacement Considerations

Direct substitutes include other ISL60002 variants with matching output voltages and accuracy grades, such as ISL60002DIH312Z-TK or ISL60002CIH312Z-TK. Verify that alternative parts maintain the same 20ppm/°C temperature coefficient and 7mA drive capability. Ensure the replacement package matches the SOT-23-3 form factor for board compatibility.
