ADM7170ACPZ-3.3 LDO Masu Gudanar da Wutar Lantarki 0.5A Hi PSRR FT LDO 3.3Vo

ADM7170 CMOS ne, ƙaramin mai sarrafa layin layi (LDO) wanda ke aiki daga 2.3 V zuwa 6.5 V kuma yana ba da har zuwa 500 mA na fitarwa na yanzu. Wannan babban fitarwa na LDO na yanzu yana da kyau don daidaita babban aikin analog da haɗaɗɗun siginar siginar da ke aiki daga 6V zuwa ƙasa 1.2 V. Yin amfani da ingantattun gine-ginen mallakar mallaka, na'urar tana ba da ƙin yarda da samar da wutar lantarki da ƙaramar amo, kuma tana samun ingantacciyar layi da ɗaukar martani na wucin gadi tare da ƙaramin ƙarfin fitarwa na yumbu na 4.7 µF. Load martani na wucin gadi shine yawanci 1.5 μs don 1 mA
zuwa mataki na 500mA.

Ana samun ADM7170 a cikin zaɓuɓɓukan ƙarfin fitarwa 17 ƙayyadaddun. Ana samun wutar lantarki mai zuwa daga hannun jari: 1.3 V, 1.8 V, 2.5 V, 3.0 V, 3.3 V, 4.2 V, da 5.0 V. Ƙarin ƙarfin lantarki waɗanda ke samuwa ta tsari na musamman sune: 1.5 V, 1.85 V, 2.0 V, 2.2 V, 2.7 V, 2.7 V, 2.7 V, 2.7 V, 2.7 V, 2.7 V, 2.7 V, 2.7 V, 2.7V 3.8 V, da 4.6 V. Hakanan ana samun sigar daidaitacce wanda ke ba da damar ƙarfin fitarwa waɗanda ke tashi daga 1.2 V zuwa VIN - VDO tare da mai raba ra'ayi na waje.

Ana iya sarrafa inrush halin yanzu ta hanyar daidaita lokacin farawa ta fitin farawa mai laushi. Lokacin farawa na yau da kullun tare da capacitor mai laushi mai laushi na 1 nF shine kusan 1.0 ms.

ADM7170 mai sarrafa ƙarar fitarwa shine 5 μV rms mai zaman kansa daga ƙarfin fitarwa. ADM7170 yana samuwa a cikin 8-lead, 3 mm × 3 mm LFCSP, yana sanya shi ba kawai bayani mai mahimmanci ba, amma kuma yana samar da kyakkyawan aikin thermal don aikace-aikacen da ke buƙatar har zuwa 500 mA na fitarwa na yanzu a cikin ƙananan ƙananan ƙafar ƙafa.
