NCV7701DWR2

Overview

The NCV7701DWR2 is a low-dropout (LDO) linear regulator manufactured by onsemi, designed for automotive applications. It provides a fixed 5 V output with a maximum continuous current of 350 mA. The device operates within an input voltage range of 4.5 V to 28 V and features a typical dropout voltage of 250 mV at full load. It includes integrated protection mechanisms such as thermal shutdown and overcurrent limiting. The component is housed in a SOIC-20 surface-mount package and is qualified to AEC-Q100 standards, ensuring reliability across an operating temperature range of -40°C to +150°C.

Feature Summary

• Integrated thermal shutdown and overcurrent protection for robust operation in harsh environments
• AEC-Q100 qualification for automotive-grade reliability and durability
• Fixed 5 V output capability suitable for powering sensitive digital logic and microcontrollers

Applications

• Automotive infotainment system power distribution
• Instrument cluster logic supply regulation
• Body control module peripheral power conditioning

Procurement Notes

Verify the specific suffix DWR2 against the official datasheet to confirm package dimensions and tape-and-reel specifications. Confirm that the AEC-Q100 grade aligns with your project's environmental requirements. Check for recent Product Change Notifications (PCNs) regarding manufacturing site changes or material declarations to ensure compliance with long-term supply agreements.

Selection Notes

Select this component when a stable 5 V rail is required for automotive loads drawing up to 350 mA. It is appropriate for designs needing high input voltage tolerance up to 28 V. Consider the SOIC-20 package size for board space constraints. Ensure the input voltage remains above the minimum threshold to maintain regulation under all expected operating conditions.

Part Context

This part belongs to the NCV7701 family of automotive LDO regulators. These devices are engineered specifically for the demanding electrical and thermal conditions found in modern vehicles. The family offers various output voltages and current capabilities to support diverse subsystems within automotive electronics architectures.

Replacement Considerations

Consult the official onsemi cross-reference documentation for verified substitutes. Ensure any replacement matches the SOIC-20 footprint, 5 V output, and 350 mA current rating while maintaining AEC-Q100 automotive qualification.
