ISL21010CFH330Z-TK

Overview

The ISL21010CFH330Z-TK is a precision micropower voltage reference IC manufactured by Renesas Electronics Corporation. It utilizes a bandgap architecture to deliver a fixed output voltage of 3.0V with an initial accuracy of ±0.2%. The device operates within an input voltage range of 3.1V to 5.5V and provides a maximum source current of 25mA. Key electrical parameters include a temperature coefficient of 50ppm/°C, a typical supply current of 48μA, and low-frequency noise characteristics suitable for sensitive analog circuits. It is housed in a compact SOT-23-3 surface-mount package.

Feature Summary

• Delivers high-precision fixed voltage output with tight initial tolerance
• Operates as a low dropout regulator with minimal quiescent current consumption
• Provides robust sourcing capability for driving downstream loads
• Maintains stability across extended industrial temperature ranges

Applications

• Battery management and monitoring systems
• Portable instrumentation requiring stable reference voltages
• Consumer and medical electronics power regulation
• Control loops and compensation networks in industrial applications

Procurement Notes

Verify the specific suffix 'TK' against the manufacturer's official documentation to confirm the tape and reel packaging configuration. Ensure the ordering part number matches the required 3.0V output variant within the ISL21010 series. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer prior to procurement.

Selection Notes

Select this component when a fixed 3.0V reference is required with high accuracy and low power consumption. The SOT-23-3 package is ideal for space-constrained designs. Consider the 25mA output current capability for direct load driving without external amplification. Verify that the minimum input voltage requirement aligns with the system's available supply rail.

Part Context

This part belongs to the ISL21010 series of micropower voltage references from Renesas. The series offers various fixed output voltage options including 1.024V, 1.25V, 1.5V, 2.048V, 2.5V, 3.0V, 3.3V, and 4.096V. All variants share similar performance characteristics regarding accuracy, noise, and package type, differing primarily in their nominal output voltage and corresponding minimum input voltage requirements.

Replacement Considerations

Compatible substitutes within the same family include ISL21010CFH333Z-TK (3.3V) and ISL21010CFH300Z-TK (3.0V). Cross-family replacements require matching pinout compatibility, output voltage, accuracy class, and package dimensions. Verify thermal performance and noise specifications against the original design requirements.
