Isilawuli somugqa
Kuelectronics, aisilawuli somugqayin ai-voltage regulatoresetshenziselwa ukugcina i-voltage engaguquki.[1]Ukumelana nomlawuli kuyahlukahluka ngokuvumelana kokubili i-voltage yokufaka kanye nomthwalo, okuholela ekuphumeni kwe-voltage njalo.Isifunda esilawulayo siyahlukahlukaukumelana, ngokuqhubekayo ukulungisa aisihlukanisi se-voltageinethiwekhi ukuze kugcinwe i-voltage ephumayo engaguquki futhi iqhubeke nokuqeda umehluko phakathi kokufakwayo nama-voltage alawulwayo njengeukumosha ukushisa.Ngokuphambene, aukushintsha isilawuliisebenzisa idivayisi esebenzayo evula futhi ivale (i-oscilates) ukuze igcine inani elimaphakathi lokuphumayo.Ngenxa yokuthi i-voltage elawulwayo yesilawuli somugqa kufanele ngaso sonke isikhathi ibe ngaphansi kune-voltage yokufaka, ukusebenza kahle kulinganiselwe futhi i-voltage yokufaka kufanele ibe phezulu ngokwanele ukuze njalo ivumele idivayisi esebenzayo ukuthi yehlise i-voltage ethile.
Izilawuli zolayini zingase zibeke isisetshenziswa esilawulayo sifane nomthwalo (shuntisilawuli) noma ingase ibeke idivayisi elawulayo phakathi komthombo nomthwalo olawulwayo (isilawuli sochungechunge).Izilawuli zomugqa ezilula zingaqukatha okuncane njenge-aI-Zener diodekanye ne-resistor yochungechunge;izilawuli eziyinkimbinkimbi zihlanganisa izigaba ezihlukene zereferensi kagesi, isikhulisi sephutha kanye nesici sokudlula amandla.Ngoba lineari-voltage regulatoriyisici esivamile samadivayisi amaningi, izilawuli ze-single-chipICszivame kakhulu.Izilawuli zomugqa zingase futhi zenziwe ngama-assemblies of discrete solid-state nomai-vacuum tubeizingxenye.
Ngaphandle kwegama labo, abalawuli bomugqa bakhonaizifunda ezingezona zomugqangoba aqukethe izingxenye ezingezona umugqa (njenge Zener diode, njengoba kukhonjisiwe ngezansi kuumlawuli we-shunt elula) futhi ngenxa yokuthi i-voltage ephumayo ayishintshile ngokufanelekile (futhi isekethe ephumayo engancikile ekufakeni kwayo iyisekhethi engaqondile.)[2]

Incazelo ye-LP5912-Q1
I-LP5912-Q1 inomsindo ophansi we-LDO onganikeza kufika ku-500 mA wokuphumayo kwamanje.Idizayinelwe ukuhlangabezana nezidingo ze-RF kanye namasekhethi e-analog, idivayisi ye-LP5912-Q1 inikeza umsindo ophansi, i-PSRR ephezulu, yamanje ethule ephansi, nomugqa ophansi kanye nokuphendula kwesikhashana komthwalo.I-LP5912-Q1 inikezela ngokusebenza komsindo ohamba phambili ekilasini ngaphandle kwe-capacitor edlula umsindo kanye nekhono lokubeka i-remote capacitance capacitance.
Idivayisi yakhelwe ukusebenza ngokokufaka kwe-1-µF kanye ne-1-µF ephumayo ye-ceramic capacitor (ayikho i-capacitor yokudlula yomsindo edingekayo).
Le divayisi itholakala ngama-voltage okukhiphayo angaguquki ukusuka ku-0.8 V kuya ku-5.5 V ngezinyathelo ezingu-25-mV.Xhumana ne-Texas Instruments Sales ngezidingo ezithile zenketho ye-voltage.
Kuwo wonke amaphakheji atholakalayo, bheka Isengezo Senketho Yephakheji (POA) ekugcineni kwaleli shidi ledatha.
