♠ TPS74401 3.0-A, I-Ultra-LDO ene-Programmable Soft-Start
I-TPS74401 i-low-dropout (LDO) i-linear regulators ibonelela ngesisombululo esilula sokulawula amandla olawulo kwiindidi ezahlukeneyo zezicelo.I-userprogrammable soft-start inciphisa uxinzelelo kumthombo wamandla wegalelo ngokunciphisa i-capacitive inrush yangoku ekuqaliseni.I-soft-start i-monotonic kwaye ilungele ukunika amandla iintlobo ezininzi ezahlukeneyo zeprosesa kunye ne-application-specific integrated circuits (ASICs).Igalelo elivumelayo kunye nemveliso yamandla-elungileyo ivumela ulandelelwano olulula kunye nabalawuli bangaphandle.Oku kuguquguquka okupheleleyo kuvumela umsebenzisi ukuba aqulunqe isisombululo esihlangabezana neemfuno zolandelelwano lwe-fieldprogrammable gate arrays (FPGAs), i-digital signal processors (DSPs), kunye nezinye izicelo ezineemfuno ezithile zokuqalisa.
Isalathiso esichanekileyo kunye ne-amplifier yephutha ihambisa ukuchaneka kwe-1% phezu komthwalo, umgca, ubushushu kunye nenkqubo.Usapho lwe-TPS74401 lwe-LDO luzinzile ngaphandle kwe-capacitor ephumayo okanye nge-ceramic output capacitors.Usapho lwesixhobo luchazwe ngokupheleleyo ukusuka kwi-TJ = -40 °C ukuya kwi-125 °C.I-TPS74401 inikezelwa kwiipakethi ezimbini ze-20-pin ezincinci ze-VQFN (i-5-mm × 5-mm RGW kunye ne-3.5-mm × 3.5-mm iphakheji ye-RGR), ivelisa ubungakanani besisombululo esipheleleyo.Kwizicelo ezifuna ukuchithwa kwamandla ongezelelweyo, ipakethe yeDDPAK (KTW) nayo iyafumaneka.
