NJM2831F03-TE1

Overview

The NJM2831F03-TE1 is a fixed-output low-dropout (LDO) voltage regulator manufactured by Nisshinbo Micro Devices. It provides a stable 3.0 V output with a maximum load current of 100 mA. The device features a typical power supply rejection ratio (PSRR) of 75 dB and an ultra-low output noise of 45 µVrms. Operating within an input voltage range of 2.3 V to 18 V, it maintains a maximum dropout voltage of 180 mV at full load. The regulator operates with a quiescent current of 180 µA and is available in a compact SOT-23-5 surface-mount package.

Feature Summary

• Provides a fixed 3.0 V output voltage with high precision regulation
• Delivers 100 mA output current capability for portable applications
• Features ultra-low output noise of 45 µVrms for sensitive circuits
• Offers high power supply rejection ratio of 75 dB

Applications

• Portable electronic devices requiring stable low-noise power
• Battery-powered systems needing efficient voltage regulation
• Communication equipment with strict noise requirements
• Microcontroller power supply rails

Procurement Notes

Verify the specific suffix TE1 against the manufacturer's official datasheet to confirm tape-and-reel packaging specifications. Ensure the part number matches the required 3.0 V output variant, as the NJM2831 series includes multiple fixed voltage options. Confirm RoHS compliance status through the latest component documentation before integration into production designs.

Selection Notes

Select this component when a fixed 3.0 V rail is required with minimal noise interference. The 100 mA current rating suits moderate load applications. Consider the 180 µA quiescent current for battery life optimization. The SOT-23-5 package allows for space-constrained PCB layouts. Verify thermal performance based on expected power dissipation within the operating temperature range.
