I-Linear Regulator
Njengoba igama laso liphakamisa, isilawuli somugqa yileso lapho ingxenye yomugqa (njengomthwalo ophikisayo) isetshenziselwa ukulawula okukhiphayo.
Kubuye kuthiwe ngezinye izikhathi isilawuli sochungechunge ngenxa yokuthi izinto zokulawula zihlelwa ngochungechunge phakathi kokokufaka nokuphumayo.
Ukushintsha Isilawuli
Isilawuli esishintshayo siyisilawuli sikagesi esisebenzisa into eshintshayo ukuze siguqule amandla angenayo abe amandla kagesi ashaya ngamandla, ebese abushelelezi kusetshenziswa ama-capacitor, inductors, nezinye izakhi.
Amandla anikezwa kusukela kokokufakayo kuya kokuphumayo ngokuvula iswishi (MOSFET) kuze kufinyelelwe i-voltage oyifunayo.
Uma i-voltage ephumayo ifinyelela inani elinqunyelwe kusengaphambili isici sokushintsha IYAVALWA futhi awekho amandla okufaka asetshenzisiwe.
Ukuphinda lo msebenzi ngesivinini esikhulu kwenza kube nokwenzeka ukuhlinzeka i-voltage ngendlela efanele futhi ngokukhipha ukushisa okuncane.

Incazelo ye-TPS7B7701-Q1
Umndeni wamadivayisi we-TPS7B770x-Q1 ufaka isilawuli esisodwa nesikabili, se-high-voltage low-dropout (LDO) esinzwa manje, esiklanyelwe ukusebenza ngebanga elibanzi lokufaka i-voltage ukusuka ku-4.5 V ukuya ku-40 V (45-V isivikelo sokulahla umthwalo ).Lawa madivaysi anikeza amandla kuzikhulisi zomsindo ophansi ze-antenna esebenzayo ngentambo ye-coax eno-300 mA isiteshi ngasinye samanje.Isiteshi ngasinye siphinde sinikeze amandla okukhipha amandla alungisekayo ukusuka ku-1.5 V kuye ku-20 V.
Lawa madivayisi ahlinzeka ngokuxilonga ngomqondo wamanje namaphinikhodi wephutha.Ukuze kuqashwe umthamo wamanje, isifunda somqondo wamanje osehlangothini oluphezulu sinikeza okukhiphayo kwe-analog okulinganayo kumthwalo ozwayo wamanje.Umuzwa wamanje onembile uvumela ukutholwa kwezimo ezivulekile, ezivamile, nezifushane ngaphandle kwesidingo sokulinganisa okwengeziwe.Umqondo wamanje ungaphindwaphindwa phakathi kwamashaneli namadivayisi ukuze kongiwe izinsiza zesiguquli se-analog-to-digital (ADC).Isiteshi ngasinye siphinde sisebenzisa umkhawulo wamanje olungisekayo ngesiphikisa sangaphandle.
I-reverse polarity diode ehlanganisiwe iqeda isidingo se-diode yangaphandle.Lawa madivayisi afaka ukuvala shaqa okujwayelekile okushisayo, ukuvikela ibhethri elifushane ukuya kwebhethri kulokho okukhiphayo, kanye nokuvikela kwamanje okuhlehliswayo.Isiteshi ngasinye sinokuvikelwa kwe-inductive clamp kulokho okukhiphayo ngesikhathi sokucisha kwe-inductive.
Lawa madivayisi asebenza ngaphezu kuka--40°C kuya ku-+125°C izinga lokushisa le-ambient.
