Conclusion

Traditional low-noise power architectures for low-noise ADCs and analog front ends often have challenges with power consumption and thermal performance. Designing with low-noise voltage references and power supplies enables designers to simplify power architectures and meet strict power budgets. Innovations in voltage references such as the REF35 are helping designers reach new levels of low noise and low power for edge devices. In noise-sensitive applications such as RF-sampling ADCs, low-noise switching regulators such as the TPS62913 allow for lower thermals compared to traditional switching regulators with an LDO.
