NCP176BMX180TCG Application Field and Working Principle NCP176BMX180TCG are specifically designed for power management in battery powered applications such as mobile phones, tablets, portable designs and high current applications. NCP176BMX180TCG is a low dropout (LDO) linear voltage regulator with very low quiescent current and provides high ripple rejection and high current capability in an ultra-compact footprint. Applications The NCP176BMX180TCG offers excellent performance in portable devices, notebook computers, digital camcorders, personal digital assistants (PDAs), wireless communications systems, and other applications requiring high accuracy, high efficiency, and low dropout. It helps to improve component and board design density, improves system efficiency and extends battery life. The NCP176BMX180TCG has a wide input and output range, making it suitable for a wide range of applications. It is also suitable for applications requiring good transient response, like USB-PD communication exchanges, in order to limit power losses due to the regulation and low quiescent current. Features The NCP176BMX180TCG offers several features that make it an attractive solution for power management systems. These include: •Ultra low quiescent current: draw only 400nA at 5V. •High voltage accuracy: 1.2% at 5V. •Fast transient response: reaching 0.2% of final value in 350us. •High ripple rejection: 80dB at 120Hz. •Operating voltage range: 0.8V to 5.5V. •High peak current capability: 2A. •Low output noise: 1.2mVrms at 100Hrz. •Internal EMI filter: 0.8μH inductor. •Internal temperature compensation: 0.2%/°C maximum change in output voltage. •Thermal shutdown: 140°C. Working Principle The NCP176BMX180TCG is a low dropout (LDO) linear voltage regulator. This regulator uses a resistive divider to provide the output voltage and low current to the load. In order to prevent saturation of the linear regulator, the input voltage has to be higher than the output voltage by a certain amount called the “dropout” voltage. In other words, the dropout voltage is the difference between the input voltage and the output voltage. The NCP176BMX180TCG uses a wide input/output voltage range from 0.8V to 5.5V, and its dropout voltage is typically 0.1V. The NCP176BMX180TCG LDO regulator also has a high accuracy of 1.2% mV at 5V. This ensures that the voltage output is stable and constant, even if the input voltage changes. The regulator also has a fast transient response time of 350μs. This means that the regulator can quickly adjust to changes in the input voltage or the load current. The NCP176BMX180TCG regulator has a very low quiescent current of only 400nA at 5V, making it ideal for battery powered applications. The regulator also has high ripple rejection of 80dB at 120Hz and low output noise of 1.2mVrms at 100Hz. The NCP176BMX180TCG also has an internal EMI filter for added protection against EMI and internal temperature compensation for improved temperature stability. Conclusion The NCP176BMX180TCG is a low dropout (LDO) linear voltage regulator that is specifically designed for power management in battery powered applications. It provides high accuracy, high efficiency, and low quiescent current in an ultra-compact footprint. The NCP176BMX180TCG has a wide input/output voltage range of 0.8V to 5.5V and has a dropout voltage of typically 0.1V. It also offers very low quiescent current, high ripple rejection, fast transient response, and low output noise. With its many features, the NCP176BMX180TCG is a great solution for power management systems.
