Procurement Notes

Verify the specific suffix Z-T7A against official Renesas documentation to confirm tape-and-reel packaging and lead-free status. Ensure the 3.2V output variant matches system requirements, as this model differs from other ISL21010 outputs like 3.3V or 4.096V. Confirm RoHS compliance details directly with the manufacturer's latest datasheet before procurement.

Selection Notes

Select this component when a precise 3.2V reference is required in a compact SOT-23-3 footprint. It is suitable for designs needing low quiescent current and high stability over temperature. Compare its 15ppm/°C drift against alternatives if tighter thermal stability is needed. Ensure input voltage remains within the 4.2V to 5.5V window for proper operation.

Part Context

This part belongs to the ISL21010 family of precision bandgap voltage references from Renesas (formerly Intersil). The family offers various fixed output voltages including 2.5V, 3.0V, 3.3V, and 4.096V. These devices are designed for general-purpose precision applications requiring small size and low power consumption.

Replacement Considerations

Direct substitutes include other ISL21010 variants with different output voltages such as ISL21010CFH333Z-T7A (3.3V) or ISL21010CFH341Z-T7A (4.096V), provided the voltage level adjustment is acceptable for the circuit design. Verify pin compatibility and thermal characteristics before substitution.
