NCP565D2TG

NCP565D2TG Description

The NCP565D2TG is a high-performance, adjustable positive linear voltage regulator from onsemi, designed to deliver up to 1.5A of continuous output current with an input voltage range up to 9V. This regulator offers an adjustable output voltage from 0.9V to 7.7V, making it highly versatile for a wide range of low-voltage applications. Packaged in a D2PAK-5 (TO-263-5) surface-mount form factor, it combines robust thermal performance with compact design. Although marked as obsolete, it remains a reliable choice for legacy designs due to its low dropout voltage (1.3V at 1.5A) and high efficiency. The device is ROHS3 compliant and REACH unaffected, ensuring environmental compliance.

NCP565D2TG Features

• Adjustable Output Voltage (0.9V–7.7V): Provides flexibility for diverse voltage requirements.
• High Current Capability (1.5A): Suitable for power-hungry applications.
• Low Dropout Voltage (1.3V @ 1.5A): Enhances efficiency in low-input-voltage scenarios.
• Excellent PSRR (85dB @ 120Hz): Minimizes noise for sensitive analog/digital circuits.
• Protection Features: Includes over-current and over-temperature safeguards.
• Low Quiescent Current (3mA): Reduces power loss in standby modes.
• Surface-Mount D2PAK-5 Package: Optimizes thermal dissipation and PCB space.

NCP565D2TG Applications

This regulator is ideal for:

• Industrial Control Systems: Stable voltage supply for sensors and microcontrollers.
• Automotive Electronics: Power management in infotainment or ADAS modules (within voltage limits).
• Consumer Electronics: Adjustable rails for set-top boxes, routers, or displays.
• Embedded Systems: Reliable regulation for FPGA/ASIC auxiliary power.
• Legacy Designs: Replacement or maintenance of older systems requiring robust 1.5A regulators.

Conclusion of NCP565D2TG

The NCP565D2TG stands out for its high current output, low dropout, and superior noise rejection, making it a strong candidate for precision power applications. While obsolete, its durable design and protection features ensure longevity in existing deployments. Engineers seeking a proven, high-performance linear regulator for medium-power systems should consider this device, especially where thermal efficiency and voltage adjustability are critical.
