ISL21080CIH341Z-TK

Overview

The ISL21080CIH341Z-TK is a fixed analog voltage reference from Renesas Electronics, providing a 4.096V output with ±0.2% initial accuracy. It operates within a supply voltage range of 2V to 5.5V and delivers up to 7mA output current. The device features ultra-low power consumption, drawing 310nA typical and 1.5µA maximum operating current. It exhibits a temperature coefficient of 50 ppm/°C, line regulation of 350 µV/V, and load regulation of 350 µV/mA. Designed for surface mount installation in a compact SOT-23 package, it functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Ultra-low power operation with typical quiescent current of 310nA
• High precision with ±0.2% initial accuracy and low temperature drift
• Compact three-pin SOT-23 surface-mount packaging

Applications

• Industrial instrumentation systems requiring stable reference voltages
• Low-power portable measurement devices
• Analog-to-digital converter (ADC) reference inputs

Procurement Notes

Verify the specific suffix '341' confirms the 4.096V output variant when ordering. Ensure the 'TK' suffix matches the required tape-and-reel packaging format for automated assembly processes. Confirm that the SOT-23-3 footprint aligns with the target PCB design constraints. Validate that the operating temperature range meets the environmental requirements of the final application.

Selection Notes

Select this component for applications demanding high precision in a minimal footprint. The ultra-low current draw makes it suitable for battery-operated systems where energy efficiency is critical. Compare line and load regulation specifications against system tolerance requirements. Consider the thermal performance within the SOT-23 package for heat dissipation needs in dense layouts.

Part Context

This part belongs to the ISL21080 series of precision voltage references from Renesas Electronics. The series offers various fixed output voltages while maintaining consistent low-power characteristics and high accuracy. These components are designed to replace older, bulkier reference solutions in modern compact electronic designs.

Replacement Considerations

Direct substitutes include other ISL21080 variants with different output voltages if the system allows voltage adjustment. Verify pinout compatibility with existing SOT-23 footprints before integrating alternative brands.
