Umlawuli womgca

Kwiizinto zombane, umlawuli womgca nguumlawuli wombaneesetyenziselwa ukugcina amandla ombane angatshintshiyo.[1]Ukuchasana komlawuli kuyahluka ngokuhambelana zombini igalelo lombane kunye nomthwalo, okubangela ukukhutshwa kombane rhoqo.Isiphaluka esilawulayo siyahlukaukuxhathisa, uhlengahlengiso oluqhubekayo aisahluli sombanewomnatha ukugcina umbane ophuma rhoqo kunye nokuqhubeka nokuchitha umahluko phakathi kwegalelo kunye nolawulo lombane njengokoinkunkuma yobushushu.Ngokwahlukileyo, aisilawuli sokutshintshaisebenzisa isixhobo esisebenzayo esivula sicime (i-oscilates) ukugcina ixabiso eliphakathi lemveliso.Ngenxa yokuba umbane olawulwayo wesilawuli somgca kufuneka uhlale ungaphantsi kombane wokungenisa, ukusebenza kakuhle kulinganiselwe kwaye igalelo lombane kufuneka libe phezulu ngokwaneleyo ukuze lihlale livumela isixhobo esisebenzayo ukuba sehlise i-voltage ethile.

Izilawuli zomgca zinokubeka isixhobo esilawulayo ngaxeshanye nomthwalo (shuntumlawuli) okanye unokubeka isixhobo esilawulayo phakathi komthombo kunye nomthwalo olawulwayo (uthotho lomlawuli).Izilawuli zomgca ezilula zinokuqulatha okuncinci njenge aZener diodekunye resistor series;abalawuli abanzima ngakumbi babandakanya izigaba ezahlukeneyo zereferensi yombane, iamplifier yempazamo kunye nesici sokudlula amandla.Kuba linearumlawuli wombaneyinto eqhelekileyo yezixhobo ezininzi, abalawuli betshiphu enyeICszixhaphake kakhulu.Izilawuli zomgca zisenokwenziwa ziiassemblies of discrete solid-state okanyeityhubhu yokufunxaamacandelo.

Ngaphandle kwegama labo, abalawuli bomgcaiisekethe ezingezizokuba ziqulathe amacandelo non-linear (ezifana Zener diodes, njengoko kubonisiwe ngezantsi kwiumlawuli we-shunt elula) kwaye ngenxa yokuba i-voltage ephumayo ihleli ngokufanelekileyo (kwaye isekethe enesiphumo esingaguqukiyo esingaxhomekekanga kwigalelo layo yisekethe engeyiyo yomgca.)[2]

Inkcazelo ye-TLV702

Uluhlu lwe-TLV702 lwabalawuli be-low-dropout (LDO) belinear zizixhobo zangoku ezipholileyo ezinomgca ogqwesileyo kunye nomthwalo wokusebenza okwethutyana.Ezi LDOs ziyilelwe izicelo amandla-ubuthathaka.I-bandgap echanekileyo kunye ne-amplifier yempazamo inika ukuchaneka okupheleleyo kwe-2%.Ingxolo ephantsi ephumayo, umlinganiselo ophezulu kakhulu wokulahlwa konikezelo lwamandla (PSRR), kunye nevolthi yokuyeka ephantsi yenza olu luhlu lwezixhobo lulungele ukhetho olubanzi lwezixhobo eziphathwa ngesandla ebhetri.Zonke iinguqulelo zesixhobo zinokuvalwa kwe-thermal kunye nomda wangoku wokhuseleko.

Ngaphaya koko, ezi zixhobo zizinzile kunye nemveliso esebenzayo ye-0.1 µF kuphela.Olu phawu luvumela ukusetyenziswa kwee-capacitors ezingabizi kakhulu ezine-voltages ephezulu ye-bias kunye nokunciphisa ubushushu.Izixhobo zilawula ukuchaneka okuchaziweyo ngaphandle komthwalo ophumayo.

Uthotho lwe-TLV702P lukwabonelela ngesekethe yokutsalwa esebenzayo ukukhupha ngokukhawuleza iziphumo.

Uluhlu lwe-TLV702 lwabalawuli bomgca we-LDO lufumaneka kwi-SOT23-5 kunye ne-1.5-mm × 1.5-mm WSON-6 iiphakheji.
