Kinetic energy can be harvested from very simple mechanical movements, like the push of a button or the turning of a knob. WePower Technologies has been able to do more with that small amount of power than I expected.

This article explores the various sources of noise in switching regulators and their impact on different analog signal chain components. It highlights several noise mitigation strategies, including the use of low dropout (LDO) regulators as effective postregulation filters. The article also shows a range of solutions from Analog Devices (ADI) that deliver optimized LDO efficiency across varying load conditions and output voltages, while pairing good power supply noise rejection. One solution offers a new method for LDOs to control the headroom provided by switching regulators with current reference architectures.
