MM3220H09NRH

Overview

The MM3220H09NRH is a fixed positive single output Low Dropout (LDO) regulator manufactured by Mitsumi Electric Co Ltd. It belongs to the MM3220 series and is designed for power supply management applications requiring stable voltage regulation. The device is classified as an electronic component within the semiconductor category, specifically under power circuits. It utilizes a surface mount package suitable for automated assembly processes in consumer electronics and industrial equipment.

Feature Summary

• Provides fixed positive single output voltage regulation
• Utilizes Low Dropout (LDO) technology for efficient power conversion
• Designed for surface mount installation

Applications

• Portable electronic devices requiring stable power rails
• Battery-powered systems needing efficient voltage regulation
• General purpose power supply circuits

Procurement Notes

Verify the specific output voltage and current rating against the official datasheet before procurement, as the model number indicates a fixed regulator but exact electrical parameters must be confirmed from the manufacturer's documentation. Ensure the package type matches the PCB footprint requirements. Check for RoHS compliance status if required by project specifications.

Selection Notes

Select this component when a fixed positive LDO regulator is required for low-noise power applications. Consider the thermal performance and maximum input voltage limits relative to the system design. Compare with other MM3220 series variants if different output voltages or package options are needed. Ensure the operating temperature range meets the environmental conditions of the target application.

Part Context

This part is part of the MM3220 series from Mitsumi Electric, which includes various battery protection ICs and regulators. While related parts like the MM3220AA1NRH focus on lithium-ion/polymer battery protection, the MM3220H09NRH is specifically a linear regulator. This distinction is critical for circuit design, as it serves a different function within power management systems.

Replacement Considerations

Consult the official datasheet for pin-compatible alternatives within the MM3220 series or cross-reference with other manufacturers offering fixed positive LDO regulators in similar packages. Verify that any substitute meets the same electrical specifications and thermal requirements.
