NJM2825F-TE1

Overview

The NJM2825F-TE1 is a precision shunt voltage reference manufactured by Nisshinbo Micro Devices. It operates within an input voltage range up to 14 V and provides a stable reference output of 13 V. The device supports a maximum output current of 12 mA, making it suitable for applications requiring a fixed high-voltage reference. It features an initial accuracy of ±0.4% and exhibits low load regulation characteristics. The component is housed in a compact SOT-23 package with five pins, designed for surface mount technology (SMT) installation. It functions reliably across an extended industrial temperature range from -40°C to +85°C.

Feature Summary

• Provides a fixed 13 V precision reference output with high initial accuracy
• Supports parallel topology operation for adjustable voltage settings via external resistors
• Features low load regulation to maintain stability under varying current conditions
• Integrated into a compact SOT-23-5 surface-mount package for space-constrained designs

Applications

• Precision power supply monitoring circuits
• Analog-to-digital converter reference sources
• Comparator threshold setting networks
• Battery management system voltage references

Procurement Notes

Verify the specific suffix TE1 corresponds to the standard tape-and-reel packaging configuration as defined by Nisshinbo Micro Devices. Confirm that the 13 V output variant matches the design requirement, as this family offers multiple fixed voltage options. Ensure the SOT-23-5 footprint aligns with the PCB land pattern specifications provided in the official datasheet. Check for RoHS compliance status if required by the target assembly process.

Selection Notes

Select this component when a fixed 13 V reference is required rather than an adjustable one. Consider the 12 mA maximum current limit against the circuit's shunt current requirements. The SOT-23-5 package is appropriate for high-density layouts. Evaluate the ±0.4% initial accuracy against the system's tolerance budget. The wide operating temperature range supports industrial environment deployment without additional thermal derating concerns.

Part Context

This part belongs to the NJM28xx series of precision shunt regulators from Nisshinbo Micro Devices. The series includes various fixed voltage options ranging from lower voltages up to 13 V. These devices are designed to replace traditional Zener diodes in applications requiring higher precision and better temperature stability. The NJM2825F specifically targets applications needing a stable 13 V reference point within a small form factor.

Replacement Considerations

Direct replacements must match the 13 V output, SOT-23-5 package, and comparable accuracy specifications. Verify pinout compatibility before substitution. Other parts in the NJM28xx family offer different fixed voltages but share similar electrical characteristics. Ensure any substitute maintains the same thermal performance and load regulation capabilities.
