NJM2872F33-TE2

Overview

The NJM2872F33-TE2 is a fixed-output low dropout (LDO) voltage regulator manufactured by Nisshinbo Micro Devices. It provides a stable 3.3 V output with a maximum continuous current of 200 mA. The device operates within an input voltage range up to 14 V and features a typical dropout voltage of 100 mV, reaching a maximum of 180 mV at 60 mA. Quiescent current is specified at 180 uA. Line regulation is 0.1 %/V, and load regulation is 0.03 %/mA. Voltage accuracy is maintained at 2 %. Power dissipation capability is 350 mW. It functions in temperatures from -40 C to +85 C and is housed in a SOT-23-5 package.

Feature Summary

• Provides high power supply rejection ratio of 75 dB for noise-sensitive applications
• Ensures low output noise with 30 uVrms specification
• Maintains stable regulation with minimal voltage drop under load

Applications

• Portable electronic devices requiring efficient power management
• Battery-powered systems needing low quiescent current operation
• Embedded circuits requiring clean 3.3 V logic supply rails

Procurement Notes

Verify the complete part number including the suffix TE2 to ensure correct packaging configuration. Confirm RoHS compliance status through official documentation before integration. Check specific datasheet revisions for any updates to electrical characteristics or thermal limits. Ensure sourcing channels provide authentic components to avoid counterfeit risks. Validate pinout compatibility with existing PCB layouts during the design phase.

Selection Notes

Select this component when a fixed 3.3 V rail is required with moderate current demands up to 200 mA. Consider the 14 V maximum input rating for systems with higher supply voltages. Evaluate the 180 uA quiescent current against battery life requirements. Compare the 100 mV typical dropout against minimum input-output differential constraints. Assess thermal performance based on the 350 mW power dissipation limit in the target environment.

Part Context

This device belongs to the NJM2872 series of LDO regulators from Nisshinbo Micro Devices. The series offers various fixed output voltages while sharing common electrical characteristics such as 200 mA output current and SOT-23-5 packaging. It serves as a linear regulation solution within the company's PMIC portfolio, targeting cost-sensitive and space-constrained consumer electronics applications.

Replacement Considerations

Compatible substitutes include other parts from the NJM2872 series with different fixed output voltages, such as NJM2872F32-TE2 for 3.2 V or NJM2872F29-TE2 for 2.9 V. Cross-reference electrical parameters like dropout voltage and quiescent current when selecting alternatives from other manufacturers.
