LDO yog dab tsi?
LDO yog cov ntawv luv ntawm Low Dropout, thiab nws yog ib qho kev tswj xyuas uas tuaj yeem ua haujlwm txawm tias muaj qhov sib txawv ntawm cov tswv yim thiab cov zis.
Qee zaum hu ua low-poob linear regulator lossis low-saturation linear regulator.
Tsis muaj tus lej txhais ntawm qhov muaj peev xwm sib txawv ntawm cov tswv yim thiab cov zis ntawm LDO. Feem ntau, nws yog hais txog tus regulator uas nws qhov qis tshaj qhov sib txawv tuaj yeem tswj tau qis dua 1V thaum lub regulator ua haujlwm ruaj khov.
Piv txwv li, rau ib qho IC uas yuav tsum muaj 3.3V fais fab mov, vim tias hom qauv tsis tuaj yeem tsim 5V rau 3.3V fais fab mov, LDO uas muaj qhov sib txawv ntawm cov tswv yim thiab cov zis yuav tsum tau qis dua.
Nyob rau hauv txoj kev no, thaum LDO outputs tib lub voltage raws li tus qauv regulator, ib tug qis input voltage kuj yuav teem.
Los ntawm kev ua haujlwm nrog qhov tsis muaj peev xwm sib txawv, lub zog poob tuaj yeem txo qis, thiab cov cua kub dissipation tuaj yeem cuam tshuam.
Siab poob
Nyob rau hauv lub linear regulator, ib tug transistor yog ntxiv los ntawm VIN rau VO. Qhov tsawg tshaj plaws muaj peev xwm sib txawv ntawm cov tswv yim thiab cov zis uas yuav tsum tau ua rau qhov transistor ua haujlwm ruaj khov yog hu ua voltage poob.
Thaum qhov sib txawv ntawm qhov sib txawv ntawm cov tswv yim thiab cov zis tawm qis dua qhov poob qis, nws nyuaj rau transistor kom muaj kev ruaj ntseg, thiab cov zis voltage yuav poob.
