onsemi Voltage Regulators - Linear NCP700MN275R2G

The NCP700MN275R2G is a linear voltage regulator from Quarktwin Technology Ltd. designed for applications requiring low noise and high power supply rejection ratio (PSRR). It provides a fixed output voltage of 2.75 V with a maximum output current of 200 mA. The device features an ultra-low noise level of approximately 15 µVrms and a PSRR of 80 dB, making it suitable for noise-sensitive RF applications such as power amplifiers in cellular phones and precision instrumentation. This regulator operates with an input voltage range of 2.5 V to 5.5 V and is stable with ceramic output capacitors as low as 1 µF. It incorporates a chip enable function for power management, a low sleep mode current of 1 µA, and includes protection features such as current limit and thermal shutdown. The NCP700MN275R2G is packaged in a compact DFN6 2x2.2 mm format, making it ideal for space-constrained designs.
