NJM2823F-TE1

Overview

The NJM2823F-TE1 is a precision micropower shunt voltage reference manufactured by Nisshinbo Micro Devices. It utilizes bipolar technology and features an internal bandgap circuit with trimming to achieve a nominal reference voltage of 1136 mV and an initial accuracy of ±0.4%. The device incorporates a temperature compensating circuit for a typical temperature coefficient of 15 ppm/°C. It operates with a maximum quiescent current of 60 µA and tolerates capacitive loads without requiring an output capacitor due to built-in phase compensation. Recommended operating conditions specify a cathode voltage range from VREF up to 13 V, with a cathode current range of 0.06 mA to 12 mA.

Feature Summary

• Built-in phase compensation circuit eliminates the need for external output capacitors while maintaining stability under capacitive loads.
• Bandgap reference circuitry provides high accuracy through factory trimming and temperature drift compensation.
• Low quiescent current consumption enables efficient power management in battery-operated or low-power applications.

Applications

• Data converters
• Instrumentation systems
• Precision measurement equipment

Procurement Notes

Verify that the component matches the specific SOT-23-5 (MTP5) package outline and the F suffix indicating ±0.4% accuracy. Confirm the TE1 tape-and-reel packaging format aligns with assembly requirements. Ensure compliance with RoHS directives as specified in the datasheet documentation before finalizing procurement orders.

Selection Notes

Select this component when a stable, low-drift reference voltage is required alongside minimal power consumption. The absence of an external capacitor requirement simplifies PCB layout and reduces bill of materials. Verify that the application's cathode current remains within the 0.06 mA to 12 mA recommended operating range to ensure optimal performance and stability.

Part Context

The NJM2823 belongs to a family of precision shunt voltage references designed for general electronic equipment. It complements other variants like the NJM2825 and NJM2820, which offer different accuracy levels and minimum operating currents. This specific part focuses on balancing high precision with ultra-low power usage suitable for portable devices.

Replacement Considerations

Direct substitutes include the NJM2825, which offers ±0.5% accuracy with a lower minimum operating current of 0.7 µA. The NJM2820 provides ±0.7% accuracy but requires a significantly higher minimum cathode current of 500 µA. Evaluate these alternatives based on specific power budget and accuracy constraints.
