Overview
The ISL21007DFB820Z-TK is a precision, low dropout micropower bandgap voltage reference IC manufactured by Intersil. It provides a fixed output voltage of 2.048V with an initial accuracy of ±0.16%. The device operates within an input voltage range of 3.2 V to 5.5 V and draws a supply current of 150µA. It is housed in an 8-SOIC package and supports an operating temperature range from -40°C to +125°C.
Feature Summary
- Precision bandgap architecture for stable voltage regulation
- Low dropout operation suitable for battery-powered systems
- Micropower consumption design for energy efficiency
Applications
- Data acquisition systems requiring precise reference voltages
- Portable instrumentation powered by limited energy sources
- Industrial control circuits needing high stability
Procurement Notes
Verify the manufacturer status as Intersil products are now part of Renesas Electronics. Confirm the specific suffix Z-TK indicates tape and reel packaging if required for automated assembly. Ensure compatibility with the 8-SOIC footprint during procurement planning.
Selection Notes
Select this component when a fixed 2.048V reference with ±0.16% accuracy is required. Consider the 150µA supply current for power budget constraints. The wide operating temperature range makes it suitable for harsh industrial environments compared to commercial-grade alternatives.
Part Context
This part belongs to the ISL21007 series of voltage references. Intersil was acquired by Renesas Electronics, which continues to support these legacy analog components. The series is known for combining precision with low power consumption in compact packages.
Replacement Considerations
Consult Renesas product legacy documents for verified substitutes. Cross-reference with other ISL21007 variants or equivalent Renesas voltage references that match the 2.048V output and 8-SOIC package requirements.
