7812 ita ce mai karkasa na injin girma wanda yawa amfani. Tana aiki don dawo da shafin, wanda ke muhimmanci saboda mai karkasa suna bukatar shafin tsakiya don tabbatar da cikin duk bangare shi aiki. Mai girman shafin 7812 ita ce mai karkasa na injin girma, wanda ke karɓar shafin mai yawa, kuma ta bayar da shafin tsakiya na 12V a cikin range na wasu shafukan shafin. Wannan zai iya samun amfani yawa a cikin wasu nau'ikan abubuwan elektronik.
A cikin TNSB (positive) mai tsinkayar voltage yana amfani da wannan abubuwa a warkas tare da transistor na pass domin kula darar transistors su ka fi tita lokacin da shiga ta ke da load. Yadda yawa elektaritici suna iya zinzanya akan shi ya kama yadda yawa voltage wannan transistor ke kula darar. Idan input voltage ita ce to high, transistor na pass zai siya elektaritici mai yawa don daina voltage zuwa ga darajar da ake bukata. Wannan hanyar 7812 voltage regulator zai iya tabbatarwa cewa output voltage basa 12 volts ne.
Shin yawa alamar da ke bayar da 7812 voltage regulator a cirkuitar elektronik. Daga cikin mahaifinta masu uku shine wanda ya bada kariya zuwa sauran kayan da ke makamashin cirkuit din. Tare da kula darar voltage a tsakanin input da output, 7812 yana kula darar tekanai ko karamin voltage wanda zai iya sabunta kayan masu mahimmanci. Mai kyau daya ne wui ne ingancin amfani da sai kuma iƙhaflar shigar da cikin wasu cirkuitar. Wannan yana sa ya kasance mai kyau ga wasu ayyukan elektronik.
Idanu 7812 ita ce mai yawa na tsarin canzawa kuma zai aiki cikin wasu nau'ikan tsarin elektoronik, kuma wani nau'i na tsarin canza zai iya amfani da shi. Tana LM317 tsarin canza voltage, wanda ke iya ba da sa 'yancin sa'aron canjiyar voltage. Amma LM317 zai iya zama mai sha'awar amfani kuma bai gama za a yi kyau ba. Wani hanyar dabi'a shine amfani da LM7805 tsarin canza voltage don ba da volts 12 sashin 5. Zai iya taimaka ga wasu tsarin da ke bukatar sa'aron canjiyar voltage. A karshe, tsarin canza 7812 voltage ita ce ainihin halin don yawa nau'ikan ayyukan elektoronik.
Idan bai ayyukan da ke sama su ka taimaka ba kuma kamar hakan kuna da matsaloli da regulatorin voltage na 7812, amsa wasu abubuwan nan: Daga cikin irin matsalar da aka iya fuskantar shi shine yawa, wanda ya haifar da shut down ko kuraƙuraren regulator. Yi amfani da regulatorin da ke da heatsink don dawo da haka. Kuma kula da duba waɗannan; suna iya haifar da canjin voltage na input output. Kwafi wannan ta kara tabbatar da voltage na input bai cancin zama sosai a alaka da specs na regulator. Idan kamar hakan yana tsaya, za a iya sauya regulator zuwa sabon.
Hinorms ya ke ƙirƙiri da thyristor, servo, da matsin gwajin stabilizer ta hanyar amfani da rashin 20 shekaru, tsoro daga cikin wasan karkatarwa, kuma aikace-ce software mai zuwa.
