NCV51190MNTAG

Overview

The NCV51190MNTAG is a linear memory termination regulator manufactured by onsemi, designed for automotive applications. It provides a fixed 1.5V output voltage with an input voltage range of 2.7V to 36V. The device delivers a maximum output current of 1A and features a low dropout voltage of 0.4V at full load. It operates within an extended temperature range from -40°C to +150°C and includes comprehensive protection mechanisms such as thermal shutdown and reverse battery protection. Packaged in a compact DFN-10 format, it ensures stable power delivery for high-speed memory interfaces.

Feature Summary

• Integrated automotive-grade linear regulator optimized for memory termination
• Built-in reverse battery protection and thermal shutdown capabilities
• Low dropout performance ensuring stability under varying load conditions

Applications

• High-speed DDR memory termination in automotive infotainment systems
• Power management for vehicle control units requiring stable 1.5V rails
• Automotive display driver power supplies

Procurement Notes

Verify the specific suffix 'TAG' against the official datasheet to confirm package type and tape/reel specifications. Confirm AEC-Q100 qualification status if required for your application. Check current lifecycle status as this component may be subject to obsolescence notices. Ensure compatibility with your PCB footprint for the DFN-10 package before ordering.

Selection Notes

Select this component when a robust, single-output 1.5V regulator is needed for automotive memory circuits. It is suitable for designs requiring wide input voltage tolerance up to 36V and high operating temperatures. Consider alternative models if higher output current or adjustable voltage settings are required. Evaluate thermal dissipation requirements based on the DFN-10 package size and expected ambient conditions.

Part Context

This part belongs to the NCV511xx series of automotive linear regulators from onsemi. These devices are engineered specifically for harsh automotive environments, offering high reliability and compliance with strict automotive standards. The series typically includes variants with different output voltages and currents, all sharing common protection features and packaging options for design flexibility.

Replacement Considerations

Check for direct substitutes within the NCV511xx family that match the 1.5V output and 1A current rating. Verify pin-to-pin compatibility with existing PCB layouts. Review updated datasheets for any changes in electrical characteristics or recommended operating conditions.
