The NCP623DM-28R2G from ON Semiconductor is a highly efficient, low dropout voltage regulator (LDO) designed to deliver a fixed output of 2.8 volts. This regulator is an excellent choice for a wide range of applications where voltage regulation with minimal power loss is crucial.

With a dropout voltage of merely 120mV at 300mA, the NCP623DM-28R2G ensures that devices maintain a stable power supply even when the input voltage is close to the output voltage. This characteristic makes it particularly suitable for battery-operated devices where maximizing the battery life is essential.

The NCP623DM-28R2G is capable of delivering an output current of up to 300mA, making it versatile for powering a variety of low-power circuits and components. Its thermal shutdown and current limit features provide additional protection, safeguarding the device and the system it powers against conditions that could lead to damage, such as overheating and overcurrent situations.

ON Semiconductor has designed this regulator with a low quiescent current, which is a mere 90µA, further enhancing its suitability for portable and battery-powered applications by reducing the power drain when in standby mode. The NCP623DM-28R2G's performance is optimized for a stable, noise-free operation, thanks to its excellent transient response and low output noise characteristics.

The device comes in a compact, surface-mount DFN-8 package, which is ideal for space-constrained applications. Its small footprint allows for integration into dense PCB layouts without sacrificing performance or requiring significant board space.

Whether you're designing power management solutions for consumer electronics, portable devices, or other applications requiring a reliable and efficient voltage source, the NCP623DM-28R2G stands out as a robust and versatile component. Its combination of low dropout performance, protection features, and energy efficiency make it an excellent choice for your next project.
