Ingcaciso yeMveliso

I-AMS1117-3.3 kunye ne-LM1117MPX-3.3 ziziphumo ezithathu zokukhutshwa komgangatho kumgangatho wokulawula umgca okhoyo kunye nokukhutshwa kwangoku kwe-1A. Ngenxa yokusebenza kwayo ngokugqwesileyo, isetyenziswa ngokubanzi.

eyona nto iphambili

Ukuhla kwamandla ombane yi-1.2V kuphela kwi-1A yemveliso yangoku, enomsebenzi okhawulelayo wangoku, umsebenzi wokhuselo nobushushu, ukuchaneka kwamandla ombane kunokufikelela kwi-1.5%.

Izikhokelo zokuSebenzisa

Kuba i-voltage yayo ephezulu yegalelo ayinakugqitha kwi-18V, ndizama ukuyigcina ingezantsi kwe-14V kwimeko enikwe ibhetri. Ukuba siyayiqhagamshela kwisiphelo sombane sokutshintshela umbane, kuhlala kucetyiswa ukuba umbane wokuphuma kombane oguqulweyo ulawulwe malunga ne-12V. Ezi zilandelayo zezona ziqhelekileyo zesekethe yesekethe yesicelo.Ii-capacitors kuzo zombini iziphelo zomfanekiso azikhuthazwa ukuba zishiywe. Umbhali wenze uvavanyo, kwindawo ezinzileyo yegalelo le-DC, amandla okuphela kwigalelo anokungashiywa, kodwa kuyacetyiswa ukuba kugcinwe uzinzo ngokubanzi. Ukongeza, ixabiso lokulungelelanisa i-capacitor linokuhlengahlengiswa ngokommandla wokusetyenziswa, kodwa ayinakuba sezantsi kune-10μF.

Ingxaki ekhethekileyo

Xa uqhagamshele ngasemva kokuphela kombane, ngamanye amaxesha umsebenzi awuzukuzinza. Ukuba akukho mpazamo kwisekethe yokuhambisa umbane ngokwawo kwisiphelo esingaphambili, kuya kufuneka sifake ukunganyangeki malunga ne-20Ω phakathi kwesiphelo sokuhambisa umbane kunye nokuphela kokufaka kwe-AMS1117-3.3. Emva kokudityaniswa, yonke isekethe inokuthi isebenze ngokwesiqhelo.

Ixabiso eliphantsi elingenye

Ngenxa yokuba le mveliso isetyenziswa eTshayina inkulu kakhulu, ke iimveliso zaseTshayina ziye zavelisa iimveliso ezineeparameter ezifanayo kunye nokupakisha. Ngenxa yokuba imveliso yamaTshayina inezibonelelo ezininzi zeendleko, ixabiso leemveliso zorhwebo laseTshayina liphantsi kakhulu. Ixabiso njengomhla wokubhalwa kweli nqaku, i-LM1117MPX-3.3NOPB1000Pcs, yi- $ 0.15624 ku-www.digikey.com kunye ne- $ 0.468 ku-www.mouser.com. Ixabiso lophawu lwesiTshayina yi- $ 0.08.
