onsemi Voltage Regulators - Linear NCP103BMX185TCG

The NCP103BMX185TCG is a low dropout (LDO) linear voltage regulator from Quarktwin Technology Ltd. designed to provide a stable output of 1.85 V with a maximum output current of 150 mA. It operates within an input voltage range of 1.7 V to 5.5 V and features a low quiescent current of approximately 50 µA, making it suitable for battery-powered applications. The device offers a typical dropout voltage of 75 mV at 150 mA and maintains an output voltage accuracy of ±1% at room temperature. This regulator is equipped with thermal shutdown and current limit protections, ensuring safe operation under various conditions. It is stable with a minimum output capacitance of 1 µF, which can be a ceramic capacitor, and has a high power supply ripple rejection ratio of 75 dB at 1 kHz. The NCP103BMX185TCG is available in a compact uDFN package measuring 1.0 x 1.0 mm, making it ideal for space-constrained applications such as mobile phones, PDAs, and portable medical equipment. The device is also RoHS compliant, Pb-free, and halogen-free.
