TPS7A20 ke "ultra-small, low-dropout" (LDO) linear regulator e ka hlahisang 300 mA ea tlhahiso ea hona joale.TPS7A20 e etselitsoe ho fana ka lerata le tlase, PSRR e phahameng, le mojaro o motle le ts'ebetso ea nakoana e ka fihlelang litlhoko tsa RF le li-circuits tse ling tse hlokolosi tsa analog.E sebelisa mekhoa e mecha ea meralo, TPS7A20 e fana ka ts'ebetso ea lerata le tlase haholo ntle le kenyelletso ea "capacitor" ea lerata.TPS7A20 e boetse e fana ka monyetla oa boemo bo tlase bo khutsitseng, bo ka ba bo loketseng bakeng sa lits'ebetso tse tsamaisoang ke betri.Ka motlakase oa ho kenya letsoho oa 1.6 V ho 6.0 V le mefuta e mengata ea tlhahiso ea 0.8 V ho 5.5 V, TPS7A20 e ka sebelisoa bakeng sa mefuta e mengata ea lisebelisoa.Sesebelisoa se sebelisa potoloho e nepahetseng ea litšupiso ho fana ka ho nepahala ho phahameng ho feta 1.5% holim'a mojaro, mohala le phapang ea mocheso.
TPS7A20 e na le mokhoa o bonolo oa ho qala o ka hare ho theola motlakase oa motlakase, kahoo o fokotsa ho theoha ha motlakase nakong ea ho qala.Sesebelisoa se tsitsitse ka li-capacitor tse nyane tsa ceramic, tse lumellang boholo bo nyane ba tharollo ka kakaretso.
TPS7A20 e na le potoloho e kenyellelitsoeng e bohlale e nang le mochini o thibelang ho hula o laoloang ka hare o bolokang LDO e holofetse le ha phini ea EN e sala e phaphametse mme e thusa ho felisa likarolo tsa kantle tse sebelisoang ho hula phini ea EN.
