onsemi Voltage Regulators - Linear NCP103AMX350TCG

The NCP103AMX350TCG is a low dropout linear voltage regulator capable of delivering up to 150 mA of output current. It operates within an input voltage range of 1.7 V to 5.5 V and is available in fixed output voltage options from 0.9 V to 3.5 V. The device features a very low quiescent current of approximately 50 µA and a standby current consumption of about 0.1 µA, making it suitable for battery-powered applications. With a typical dropout voltage of 75 mV at 150 mA, the NCP103AMX350TCG provides high accuracy of ±1% at room temperature and offers excellent power supply ripple rejection of 75 dB at 1 kHz. It includes thermal shutdown and current limit protections, ensuring safe operation. The regulator is stable with a minimum output capacitance of 1 µF, and it is packaged in a compact uDFN 1.0 x 1.0 mm form factor. The device is also RoHS compliant and free from halogens and lead. Typical applications include portable medical equipment, mobile phones, and other noise-sensitive devices, making it a versatile choice for engineers looking for reliable voltage regulation in constrained spaces.
