Power Quencher® LDOs: This series of low-power, fully-integrated low dropout (LDO) voltage regulators achieves a low-noise output voltage without external components, thus saving package pins and valuable PC board space. These LDOs are silicon-proven in the TSMC 40 nm ULP process and are a part of our 40 nm integrated power management unit (PMU) IP core series that has been optimized for integration into Application Specific Integrated Circuits (ASICs) or Systems-on-a-Chip (SoCs), including radio frequency (RF), wireless, and narrowband Internet of Things (NB-IoT) applications.
