NCV70521MN003G

Overview

The NCV70521MN003G is a fixed-output Low Dropout (LDO) linear regulator manufactured by onsemi. It provides a fixed 3.0 V output voltage with a maximum load current capability of 150 mA. The device operates within an input voltage range of 1.8 V to 6.0 V and features ultra-low quiescent current, typically 4 µA, to minimize power consumption in battery-powered applications. It incorporates comprehensive protection mechanisms including thermal shutdown, reverse polarity protection, and overcurrent limiting. The component is housed in a compact DFN-6 package measuring 2 mm x 2 mm, suitable for space-constrained designs.

Feature Summary

• Ultra-low quiescent current design minimizes standby power drain
• Integrated reverse polarity protection safeguards against incorrect supply connections
• Compact DFN-6 footprint optimizes board space utilization
• Robust protection suite includes thermal shutdown and overcurrent limiting

Applications

• Battery-operated portable consumer electronics
• Wearable health monitoring devices
• IoT sensor nodes requiring low power consumption
• Mobile communication equipment

Procurement Notes

Verify the specific suffix 'MN003G' matches the required 3.0 V output voltage during procurement. Confirm that the DFN-6 package dimensions align with your PCB layout constraints. Ensure the selected supplier provides components compliant with RoHS standards and free from halogens. Cross-reference the ordering part number with official onsemi documentation to avoid substitution errors.

Selection Notes

Select this LDO when a stable 3.0 V rail is required with minimal static current draw. It is appropriate for systems where input voltage varies between 1.8 V and 6.0 V. Consider its small package size for dense layouts. Evaluate if the 150 mA current limit meets peak load demands. Verify thermal performance under expected ambient conditions.

Part Context

This component belongs to onsemi's NCV705xx series of low-dropout regulators designed for high-efficiency power management. The series targets applications demanding low noise and high power supply rejection ratio (PSRR). The NCV prefix indicates automotive-grade qualification, ensuring reliability in harsh environments. This family supports various fixed output voltages to accommodate different logic levels.

Replacement Considerations

Check for pin-compatible alternatives within the same NCV705xx series offering different output voltages. Verify equivalent electrical characteristics such as dropout voltage and PSRR. Ensure any substitute maintains the same DFN-6 package and thermal properties. Confirm availability of automotive-grade versions if required.
