LDO, kapena low dropout regulator, ndi chowongolera chotsika chotsika chomwe chimagwiritsa ntchito transistor kapena field effect chubu (FET) yomwe imagwira ntchito m'dera lake la saturation kuti ichotse ma voltage ochulukirapo pamagetsi omwe amagwiritsidwa ntchito kuti apange voteji yoyendetsedwa bwino.
Zinthu zinayi zazikulu ndi Dropout, Noise, Power Supply Rejection Ratio (PSRR), ndi Quiscent Current Iq.
Zigawo zazikuluzikulu: gawo loyambira, gawo lokhazikika lomwe limayambira nthawi zonse, gawo lothandizira, kusintha zinthu, gwero lachidziwitso, chokulitsa cholakwika, network resistor network ndi chitetezo, etc.
