The Renesas ISL21080CIH330Z-TK is a series voltage reference from the FGA™ family, delivering a fixed 3V output with ±0.2% initial tolerance. It draws only 1.5µA of supply current, making it a strong fit for battery-powered instrumentation, portable medical devices, and low-power sensor interfaces where every microamp matters.
Renesas lists the ISL21080CIH330Z-TK as Active and ROHS3 compliant. For dual-sourcing resilience, the FGA™ series includes several fixed-output voltage options in the same SOT-23-3 footprint, but no pin-compatible second source from another manufacturer is recorded in the available documentation.
