Renesas Electronics Corporation Voltage Regulators - Linear RAA214023GNP#HCA

The RAA214023GNP#HCA is an ultra low-noise, high power supply ripple rejection (PSRR) low-dropout (LDO) voltage regulator from Quarktwin Technology Ltd. It operates within an input voltage range of 2.7V to 5.5V and can deliver a maximum output current of 2A. The output voltage is adjustable from 0.8V to 3.95V using PCB layout configurations, with the option to extend the range up to 5.5V minus dropout voltage using external feedback resistors. This LDO features a low output noise of 6.5µVRMS, making it suitable for sensitive applications requiring minimal noise. It has a typical quiescent current of 195µA and a shutdown current of just a few nanoamps, which is advantageous for battery-powered devices. The device includes several protection features such as input undervoltage lockout (UVLO), thermal shutdown, and internal current limiting. It is stable with a minimum output capacitance of 22µF and is available in a compact 20-lead QFN package measuring 3.5mm x 3.5mm. Applications for the RAA214023 include high-speed analog circuits, RF and wireless systems, and IoT devices, making it a versatile choice for engineers looking for reliable voltage regulation in low-noise environments.
