The NJU7201U55 type of voltage regulator belongs to the PMIC (Power Management IC) family, specifically to the Voltage Regulators - Linear section. This device provides an efficient CV/CR mode of Discharge/Charge/Switch regulator and Switch Management, which features very low power dissipation. It is manufactured by Nippon Chemi-Con and it is equipped with an on-chip buck-boost–mode switching regulator, an internal clock generator and an integrated RTC timer. This type of voltage regulator is widely used in embedded systems and various application fields. It is used to step-down input voltage levels to regulated output voltage levels. In some applications, it can also be used to step-up the input voltage level depending on the device configuration. The NJU7201U55 has three different working modes: Constant Current (CC mode), Constant Voltage/Constant Resistance (CV/CR mode) and Switching Mode (SM mode). In the CC mode, the input voltage is regulated to the device’s nominal output voltage. The device\'s output will remain constant regardless of the input voltage change. This guarantees stable output for the load.In the CV/CR mode, the device is able to maintain a constant voltage when operating in CC mode, while also allowing a constant current to flow. In this mode, the output voltage is always kept as close as possible to the input voltage, while the current is regulated to the desired level. This makes the NJU7201U55 suitable for powering sensitive loads, such as LED backlighting or LCD displays.In the SM mode, the device will monitor the input and output voltage levels and will switch between modes to provide the most efficient power transfer. This mode is typically used in applications where power efficiency is essential, such as battery-powered systems or low-power automotive devices.The NJU7201U55 is suitable for a wide range of voltage regulation applications and offers excellent performance and flexibility. It is easy to configure and offers a wide input and output voltage range and low quiescent current. The device also has integrated protection features, such as overload protection, thermal shutdown and overvoltage protection, which make it suitable for many industrial and automotive applications.
