♠ Isilawuli samandla ombane esihlengahlengiswayo nesisisigxina
I-LD1117 yi-low drop voltage regulator ekwazi ukubonelela ukuya kwi-800 mA yemveliso yangoku, ekhoyo nakwi-adjustable version (VREF = 1.25 V). Ngokubhekiselele kwiinguqulelo ezisisigxina, zinikezelwa ezi zixhobo zilandelayo zombane: 1.2 V, 1.8 V, 2.5 V, 2.85 V, 3.3 V kunye ne-5.0 V.
Isixhobo sinikezelwa kwi: SOT-223, DPAK, SO-8 kunye ne-TO-220. I-SOT-223 kunye ne-DPAK iipakethi zokunyuka komphezulu ziphucula iimpawu ze-thermal nokuba zibonelela ngesiphumo esifanelekileyo sokugcina indawo. Ukusebenza okuphezulu kuqinisekiswa yi-NPN pass transistor. Enyanisweni kule meko, ngokungafaniyo ne-PNP enye, i-current current iqukuqela kakhulu kumthwalo. Kuphela i-10 µF encinci ye-capacitor eqhelekileyo efunekayo ukuzinza. Kwi-chip trimming ivumela umlawuli ukuba afikelele kwimveliso eqinile yokunyamezela amandla ombane, ngaphakathi kwe-± 1 % kwi-25 °C.
I-LD1117 ehlengahlengiswayo yipini yokukhonkotha iyahambelana nomnye umgangatho. Izilawuli zamandla ombane ezihlengahlengiswayo zigcina ukusebenza ngcono ngokwemiqathango yokuhla nokunyamezela.
• Umbane wokuyeka umbane osezantsi (uhlobo olu-1 lwe-V.)
• 2.85 V ukusebenza kwesixhobo kulungele i-SCSI-2 ukupheliswa okusebenzayo
• Imveliso yangoku ukuya kuthi ga kwi-800 mA
• Umbane wesiphumo esisisigxina: 1.2 V, 1.8 V, 2.5 V, 3.3 V, 5.0 V
• Ukufumaneka koguqulelo oluhlengahlengiswayo (VREF = 1.25 V)
• Umda wangaphakathi kunye ne-thermal
• Ifumaneka ± 1 % (ku-25 °C) kunye ne-2 % kuluhlu olupheleleyo lobushushu
