Abstract: Disclosed is a digital LDO regulator capable of performing asynchronous binary search using a binary-weighted PMOS array. The digital LDO regulator includes a PMOS array unit including a binary-weighted PMOS array and that binary searches the PMOS array asynchronously, and a mode determining unit that operates in at least one of a fine mode, a coarse mode, and a medium mode, based on an output voltage of the PMOS array unit.

Abstract: The present invention relates to novel enzyme nanoparticles capable of converting methane into methanol, in which key active sites of methane-oxidizing bacteria are fused with each other and expressed on a protein that can be self-assembled in cells to form nanoparticles, and specifically to enzyme nanoparticles including a protein having methane monooxygenase (MMO) activity and active sites of the methane oxidase, a method for production thereof, a recombinant microorganism into which a nucleic acid encoding the protein and the active site of the methane oxidase is introduced, and immobilized enzyme nanoparticles including the enzyme nanoparticles loaded on a carrier.
