NCV7120FP0R2G

Overview

The NCV7120FP0R2G is a high-voltage linear regulator manufactured by onsemi, designed for automotive applications. It features an output voltage of 5V with a maximum load current of 1A. The device operates within an input voltage range of 4.5V to 36V and includes comprehensive protection mechanisms such as thermal shutdown, overcurrent protection, and reverse battery protection. It is housed in a compact DPAK-3 surface-mount package, ensuring reliable performance across the specified industrial temperature range.

Feature Summary

• Integrated reverse battery protection safeguards against incorrect polarity connections
• Built-in thermal shutdown prevents damage during overheating conditions
• Overcurrent protection limits output current to protect the regulator and load

Applications

• Automotive electronic control units (ECUs)
• Infotainment systems power supply
• Sensor interface circuits requiring stable 5V regulation

Procurement Notes

Verify the component authenticity through authorized distributors or direct manufacturer channels. Confirm that the part number matches exactly NCV7120FP0R2G, noting the specific suffix indicates the tape and reel packaging format. Ensure compliance with RoHS directives and check for any recent product change notifications regarding pinout or electrical characteristics before finalizing procurement orders.

Selection Notes

Select this regulator when a robust, single-output 5V supply is needed for automotive electronics. It is suitable for environments with noisy power lines due to its wide input range and built-in protections. Consider the DPAK-3 package for space-constrained PCB layouts. Evaluate thermal requirements based on the expected load current and ambient temperature to ensure adequate heat dissipation without additional heatsinks.

Part Context

This component belongs to onsemi's family of high-voltage linear regulators tailored for automotive markets. It complements other voltage regulators in the portfolio by offering a fixed 5V output with high current capability. The NCV7120 series is engineered to meet stringent automotive reliability standards, providing a stable reference voltage for sensitive digital and analog circuits in vehicle systems.

Replacement Considerations

Check for cross-reference parts like MC78L05 variants if lower current is acceptable, but verify pin compatibility. Direct replacements must support 36V input and 1A output. Consult onsemi documentation for updated equivalents within the same regulatory family.
