Inkcazelo ye-TPS7A20
I-TPS7A20 yi-ultra-small, low-dropout (LDO) yokulawula umgca onokuthi uvelise i-300 mA yemveliso yangoku.I-TPS7A20 yenzelwe ukubonelela ngengxolo ephantsi, i-PSRR ephezulu, kunye nomthwalo obalaseleyo kunye nomgca wokusebenza okwethutyana onokuhlangabezana neemfuno zeRF kunye nezinye iisekethe ze-analog ezinovakalelo.Isebenzisa ubuchule bokuyila obutsha, i-TPS7A20 ibonelela ngentsebenzo yengxolo ephantsi kakhulu ngaphandle kokongezwa kwecapacitor yengxolo.I-TPS7A20 ikwabonelela ngenzuzo ye-low-quiescent current, enokuthi ilungele usetyenziso olunamandla ebhetri.Ngoluhlu lwe-voltage yegalelo le-1.6 V ukuya kwi-6.0 V kunye noluhlu oluphumayo lwe-0.8 V ukuya kwi-5.5 V, i-TPS7A20 ingasetyenziselwa iintlobo ezahlukeneyo zezicelo.Isixhobo sisebenzisa isiphaluka esichanekileyo sereferensi ukubonelela ngokuchaneka okuphezulu kwe-1.5% phezu komthwalo, umgca, kunye nokutshintsha kweqondo lokushisa.
I-TPS7A20 ibonakalisa isiqalo esithambileyo sangaphakathi ukuthoba i-inrush yangoku, ngaloo ndlela kuncitshiswe ukuhla kwamandla ombane ngexesha lokuqalisa.Isixhobo sizinzile kunye ne-ceramic capacitors encinci, evumela ubungakanani besisombululo esincinci.
I-TPS7A20 ine-smart yenza i-input circuit circuit kunye ne-internal controlled pulldown resistor egcina i-LDO ikhubazekile naxa i-pin ye-EN ishiywe idada kwaye inceda ukuphelisa amacandelo angaphandle asetyenziselwa ukukhupha i-EN pin.
1. Ngoobani abasebenzi kwisebe lakho le-R & D?Ziziphi iziqinisekiso zakho?
