♠ 6.5 V, 500 mA, ingxolo ephantsi, i-PSRR ephezulu, i-CMOS LDO yokuphendula ngokukhawuleza
I-ADM7170 yi-CMOS, i-low dropout linear regulator (LDO) esebenza ukusuka kwi-2.3 V ukuya kwi-6.5 V kwaye inikezela ukuya kwi-500 mA yemveliso yangoku. Le mveliso ephezulu ye-LDO yangoku ilungele ukulawulwa kwe-analog yokusebenza ephezulu kunye neesekethe zesignali ezixubileyo ezisebenza ukusuka kwi-6 V ukuya kwi-1.2 V iileyili. Sisebenzisa ulwakhiwo olukwizinga eliphezulu lobunikazi, isixhobo sibonelela ukwaliwa konikezelo lwamandla aphezulu kunye nengxolo ephantsi, kwaye siphumeza umgca ogqwesileyo kunye nomthwalo wokuphendula okwexeshana nge-4.7 µF encinci yecapacitor ye-ceramic. Umthwalo wokuphendula okwexeshana udla ngokuba yi-1.5 μs kwi-1 mA
ukuya kwi-500 mA inyathelo lomthwalo.
I-ADM7170 ifumaneka kwiinketho ze-voltage ezisisigxina ezili-17. Amandla ombane alandelayo afumaneka kwisitokhwe: 1.3 V, 1.8 V, 2.5 V, 3.0 V, 3.3 V, 4.2 V, kunye ne-5.0 V. Izixhobo ezongezelelweyo ezifumanekayo ngomyalelo okhethekileyo zezi: 1.5 V, 1.85 V, 2.0 V, 2.2 V, 2.5 V, 2.8 V, 2.8 V, 2.8 V, 2.8 I-3.8 V, kunye ne-4.6 V. Uguqulelo oluhlengahlengiswayo lukwakhona oluvumela i-voltage ye-output ukusuka kwi-1.2 V ukuya kwi-VIN - i-VDO ene-feedback divider yangaphandle.
I-Inrush current inokulawulwa ngokulungelelanisa ixesha lokuqalisa ngokusebenzisa ipini yokuqalisa ethambileyo. Ixesha eliqhelekileyo lokuqalisa kunye ne-1 nF soft start capacitor malunga ne-1.0 ms.
I-ADM7170 ye-regulator output ingxolo yi-5 μV rms ezimeleyo kwi-voltage ephumayo. I-ADM7170 ifumaneka kwi-8-lead, 3 mm × 3 mm LFCSP, okwenza ukuba ingabi yisisombululo esincinci kakhulu, kodwa ibonelela ngokusebenza kakuhle kwe-thermal kwizicelo ezifuna ukuya kwi-500 mA yemveliso yangoku kwinqanaba elincinci, eliphantsi.
