The NCV8674DS50G is an adjustable low-dropout (LDO) linear voltage regulator with an output voltage range of 0.9V to 8.0V. It is designed for applications requiring low quiescent current, low output noise, high PSRR and low EMI. The device can deliver up to 50mA of output current, enough to power tiny microprocessors, memories, power amplifiers, and other loads.

The NCV8674DS50G is designed to maintain a precise output voltage irrespective of the load. It operates over a wide input voltage range from 2.1V to 22V, making it suitable for battery-powered, USB-powered, and automotive applications. The device is capable of achieving a high PSRR of 46dB, thereby reducing high-frequency noise across the input supply. It includes a power-good indicator, which ensures an error-free shutdown if the output voltage falls below the regulation threshold.

The high power efficiency of the NCV8674DS50G is further enhanced by its ultra-low quiescent current of 1uA, making it ideal for extended battery life in wearables and other portable applications. The LDO’s level shift circuit helps reduce electromagnetic interference (EMI) at the output, ensuring that outputs meet the strictest standards for EMI.

Application Fields

The NCV8674DS50G is a highly suitable LDO for applications such as handheld portable electronics, mobile phones, and other energy-management applications. The device is also well-suited for powering small digital-to-analog and analog-to-digital converters, audio amplifiers, and low-voltage microcontrollers.

Working Principle

The NCV8674DS50G is a linear voltage regulator that operates by dropping the input voltage to its required output voltage level. It consists of an internal amplifier that is connected to a potentiometer. The regulator monitors the output voltage and adjusts the resistance of the potentiometer to ensure that the output voltage is maintained. The device is capable of delivering up to 50mA of output current while maintaining a high level of accuracy.

The device includes several features that help ensure an accurate and reliable output voltage during operation. It includes a power-good indicator, which will ensure an error-free shutdown if the output voltage falls below the regulation threshold. The device also includes an undervoltage lockout (UVLO) and thermal shutdown protection, which helps protect the device from damage in the event of a malfunction or excessive heat.

The NCV8674DS50G also offers a high power efficiency due to its ultra-low quiescent current. Its level shift circuit helps reduce EMI and improve power efficiency. The device operates over a wide input voltage range from 2.1V to 22V, making it ideal for battery-powered, USB-powered and automotive applications.

Overall, the NCV8674DS50G is an excellent choice for a wide range of applications due to its low quiescent current, high PSRR, and low EMI. Its adjustable output voltage and wide input voltage range make it suitable for a variety of applications.
