ON Semiconductor NCP161AFCT280T2G LDO Voltage Regulator

The NCP161AFCT280T2G from ON Semiconductor is a high-performance low-dropout (LDO) linear voltage regulator designed to deliver a stable and precise output voltage. This LDO is particularly suitable for battery-powered applications due to its low quiescent current and high power supply rejection ratio (PSRR).

Key Features:

• Output Voltage: 2.8V fixed output, providing a stable voltage for a wide range of applications.
• High Accuracy: Output voltage accuracy is maintained within ±1%, ensuring reliable operation of sensitive electronic circuits.
• Low Dropout: The low dropout voltage allows the regulator to continue delivering a regulated output even when the supply voltage is close to the output voltage, maximizing battery life.
• Low Quiescent Current: With a typical quiescent current of just 1µA, the NCP161AFCT280T2G is optimized for battery-powered devices, helping to extend battery life.
• High PSRR: Excellent power supply rejection ratio of 75dB at 1kHz minimizes output voltage fluctuations due to variations in the input voltage, providing a more stable output.
• Thermal Shutdown: Integrated thermal shutdown feature protects the device from damage due to overheating.
• Current Limit Protection: Built-in current limit protection prevents damage to the regulator and the downstream circuitry from high current conditions.
• Package: Available in a compact, 5-terminal SC-70 package, which is ideal for space-constrained applications.
