Overview
The ISL21080DIH309Z-TK is a fixed voltage reference from the Renesas ISL21080 series, housed in a SOT-23-3 surface-mount package. It provides a 3V output with an initial accuracy of ±0.2% and a temperature coefficient of 50 ppm/°C. The device operates within an input voltage range of 2V to 5.5V and delivers a maximum shunt current of 7mA. It functions reliably across a temperature range of -40°C to +85°C, featuring line regulation of 350 μV/V and load regulation of 350 μV/mA.
Feature Summary
- Series topology precision voltage reference design
- High initial accuracy for stable reference performance
- Low temperature coefficient for thermal stability
Applications
- Precision analog-to-digital converter (ADC) references
- Digital-to-analog converter (DAC) voltage sources
- Portable instrumentation requiring low power consumption
Procurement Notes
Verify the specific suffix 'DIH309Z-TK' against official Renesas documentation to confirm the exact output voltage and tolerance grade. Ensure the ordering code matches the required pinout and packaging specifications for your PCB layout. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when a fixed 3V reference is required with high accuracy in a compact SOT-23-3 footprint. Consider the 7mA output current capability and 5.5V maximum input voltage limits during circuit design. Evaluate the 50 ppm/°C temperature coefficient against your system's thermal operating environment requirements.
Part Context
This part belongs to the ISL21080 family of micropower precision voltage references by Renesas Electronics. The family offers various fixed output voltages and accuracies in small packages. The ISL21080 series is designed for battery-powered applications where low quiescent current and high precision are critical for maintaining signal integrity.
Replacement Considerations
Check for ISL21080 variants with different output voltages or tolerances if electrical parameters differ. Verify pin compatibility with other SOT-23-3 voltage references before substitution.
