♠ TPS785-Q1 Izimoto, 1-A, High-PSRR Low-Dropout Voltage Regulator Ngokunemba Okuphezulu Nokunika amandla
I-TPS785-Q1 ultra low-dropout regulator (LDO) iyi-LDO yamanje encane, ephansi ethule engakwazi ukuthola u-1 A ngomugqa omuhle kakhulu futhi ilayishe ukusebenza kwesikhashana.
Umsindo ophumayo ophansi nokusebenza okuhle kwe-PSRR kwenza idivayisi ifaneleke emithwalweni ye-analog ezwela amandla. I-TPS785-Q1 iyidivayisi evumelana nezimo yokulawula okuthunyelwe ngenxa yokuthi le divayisi isekela ububanzi bevoltheji yokufaka ukusuka ku-1.7 V ukuya ku-6.0 V futhi inikeza ububanzi obulungisekayo bokuphumayo obungu-1.2 V ukuya ku-5.5 V. Le divayisi iphinde ibe nama-voltage okukhiphayo angaguquki ukusuka ku-0.65 V kuya ku-5.0 V ukuze inike amandla ama-voltage avamile.
I-TPS785-Q1 inikeza umkhawulo wamanje wokugoqa ukuze unciphise ukuchithwa kwamandla ngesikhathi sesimo esingaphezu kwamanje. Okokufaka kwe-EN kusiza ngezimfuneko zokulandelana kwamandla kwesistimu. I-soft-start yangaphakathi ihlinzeka ngokuqalisa okulawulwayo kunciphisa i-inrush current okuvumela amandla okufaka aphansi azosetshenziswa.
I-TPS785-Q1 ihlinzeka ngomjikelezo wokudonsela phansi osebenzayo ukuze ukhiphe ngokushesha imithwalo yokuphumayo lapho ikhutshaziwe.
