The NCP114AMX280TBG is a high-performance, low dropout voltage regulator (LDO) designed and manufactured by ON Semiconductor. This LDO regulator is engineered to provide a stable and reliable power supply for a wide range of applications, particularly those requiring a low voltage drop and low noise performance.

Key Features

• Output Voltage: The device offers a fixed output voltage of 2.8V, which is ideal for powering sensitive analog and digital circuits that require precise and constant voltage levels.
• High Accuracy: With an output voltage accuracy of ±1%, the NCP114AMX280TBG ensures that the connected components receive a stable voltage, minimizing the risk of malfunctions due to power supply variations.
• Low Dropout: The low dropout voltage (typically 135 mV at 300 mA) allows the regulator to maintain output voltage regulation with minimal input-to-output voltage differential, making it highly efficient in battery-operated devices.
• High PSRR: The device boasts an excellent power supply rejection ratio (PSRR) of 75 dB at 1 kHz, which significantly reduces the effects of supply voltage variations on the output voltage, thereby providing cleaner power to sensitive loads.
• Thermal Protection: The built-in thermal shutdown feature protects the device from damage due to excessive temperature, enhancing the longevity and reliability of both the regulator and the overall system.
• Current Limit: The current limit function safeguards the device and the load from damage caused by overcurrent conditions.
