• Portable instrumentation devices
• Consumer and medical electronics

Procurement Notes

Verify the specific suffix 'Z-T7A' against official Renesas documentation to confirm tape-and-reel packaging and lead-free status. Ensure the input voltage supplied to the circuit exceeds the minimum requirement of 3.4V for proper operation. Confirm that the thermal environment remains within the -40°C to +125°C range to maintain specified accuracy levels during procurement and integration.

Selection Notes

Select this component when a fixed 3.0V reference with high precision is required in space-constrained designs. The SOT-23-3 package offers a compact footprint suitable for portable applications. Consider the 150mV dropout voltage when designing for battery-powered systems nearing end-of-life discharge levels. The low quiescent current makes it suitable for extending battery life in standby modes compared to higher current alternatives.

Part Context

This part belongs to the ISL21010 series of micropower voltage references. The series includes various output voltage options such as 1.024V, 2.5V, and 3.3V, all sharing similar precision and low-power characteristics. The ISL21010CFH330 variant specifically targets applications requiring a 3.0V rail, distinguishing it from other series members through its fixed output configuration while maintaining the same core architecture and package style.

Replacement Considerations

Direct substitutes within the ISL21010 family include ISL21010CFH333Z-T7A (3.3V) or ISL21010CFH250Z-T7A (2.5V) if voltage adjustment is permissible. Verify pinout compatibility across SOT-23-3 packages before substitution. Cross-reference with Intersil legacy part numbers if migrating from older design generations.
