♠ TPS785-Q1 Izithuthi, i-1-A, i-High-PSRR i-Low-Dropout Voltage Regulator ngokuchaneka okuphezulu kunye nokuVumela
I-TPS785-Q1 i-ultra low-dropout regulator (LDO) yincinci, i-LDO yangoku epholileyo ephantsi enomthombo we-1 A kunye nomgca obalaseleyo kunye nomthwalo wokusebenza okwethutyana.
Ingxolo yemveliso ephantsi kunye nokusebenza okukhulu kwe-PSRR kwenza isixhobo silungele imithwalo ye-analog enamandla. I-TPS785-Q1 iyisixhobo esiguquguqukayo sokulawulwa kweposi ngenxa yokuba esi sixhobo sixhasa igalelo lombane wegalelo ukusuka kwi-1.7 V ukuya kwi-6.0 V kwaye inikezela ngoluhlu lwemveliso elungelelanisiweyo ye-1.2 V ukuya kwi-5.5 V. Isixhobo sikwabonisa i-voltage echanekileyo yokuphuma kwi-0.65 V ukuya kwi-5.0 V yokunika amandla ombane oqhelekileyo.
I-TPS785-Q1 inikezela ngomda wangoku wokugoba ukuze unciphise ukuchithwa kwamandla ngexesha elingaphezulu kwemeko yangoku. Igalelo le-EN linceda ngeemfuno zolandelelwano lwamandla enkqubo. I-soft-start yangaphakathi inika isiqalo esilawulwayo sokunciphisa i-inrush yangoku ivumela ukuba igalelo eliphantsi lisetyenziswe.
I-TPS785-Q1 ibonelela ngesekethe yokutsalwa esebenzayo ukukhupha ngokukhawuleza imithwalo yemveliso xa ivaliwe.
