Linear regulator
Inzvemagetsi, mutsetse wemutsetse ndiye avoltage regulatorinoshandiswa kuchengetedza voltage yakatsiga.[1]Kupokana kweiyo regulator kunosiyana zvichienderana nezvose zviri zviviri vhezheni yekupinza uye mutoro, zvichikonzera kubuda kwemagetsi nguva dzose.Iyo yekudzora yedunhu inosiyana yayoresistance, kuramba uchigadzirisa avoltage dividernetwork kuchengetedza inogara ichibuda voltage uye ichiramba ichibvisa mutsauko pakati peiyo inopinza uye inodzorwa voltages setsvina inopisa.Kusiyana neizvi, aswitching regulatorinoshandisa mudziyo unoshanda unobatidza nekudzima (oscilates) kuchengetedza avhareji kukosha kwekubuda.Nekuti iyo yakadzorwa voltage yemutsara regulator inofanirwa kugara yakadzikira pane yekupinza voltage, kushanda zvakanaka kune kushoma uye magetsi ekuisa anofanirwa kunge akakwira zvakakwana kuti agare achibvumira chishandiso chinoshanda kudonhedza imwe voltage.
Linear regulators vanogona kuisa mudziyo wekudzora wakafanana nemutoro (shuntregulator) kana inogona kuisa mudziyo wekudzora pakati pechitubu uye mutoro wakadzorwa (akateedzana regulator).Rakareruka mitsara regulator inogona chete iine zvishoma seaZener diodeuye akatevedzana resistor;mamwe akaomesesa maregulator anosanganisira akaparadzana matanho evolti referensi, kukanganisa amplifier uye simba pass element.Nokuti linearvoltage regulatorchinhu chakajairika chemidziyo yakawanda, single-chip regulatorsICszvakajairika.Linear regulator inogona zvakare kugadzirwa nemagungano e discrete solid-state kanavacuum tubezvikamu.
Pasinei nezita ravo, linear regulators varinon-linear circuitsnekuti iwo ane zvisiri-mutsara zvikamu (seZener diodes, sezvinoratidzwa pazasi munesimple shunt regulator) uye nekuti iyo voltage inobuda inogara iripo (uye dunhu rine chisingaperi chinobuda chisingaenderane nekupinza kwayo idunhu risiri-mutsara.)[2]

Tsanangudzo yeTLV702
Iyo TLV702 yakatevedzana yeyakaderera-dropout (LDO) mutsara mitsara yakaderera yakadzikama yazvino michina ine yakanakisa mutsara uye inotakura kuita kwechinguvana.Aya maLDO akagadzirirwa maapplication anonzwa simba.Iyo chaiyo bandgap uye kukanganisa amplifier inopa yakazara 2% kunyatsoita.Ruzha rwakaderera rwakabuda, yakanyanya simba-supply rejection ratio (PSRR), uye yakaderera-dropout voltage inoita iyi nhevedzano yemidziyo yakanakira sarudzo yakakura yebhatiri-inofambiswa nemaoko emidziyo.Ese mavhezheni ezvishandiso ane kudzima kwemafuta uye muganho wazvino wekuchengetedza.
Uyezve, michina iyi yakagadzikana ine inoshanda yekubuda capacitance ye 0.1 µF chete.Ichi chimiro chinogonesa kushandiswa kweanodhura-anoshanda capacitor ane yakakwirira bias voltages uye tembiricha inoderera.Midziyo inogadzirisa kune yakatsanangurwa nemazvo pasina mutoro wekubuda.
Iyo TLV702P yakatevedzana inopawo inoshanda yekudhonza dunhu kuti ikurumidze kuburitsa zvinobuda.
Iyo TLV702 yakatevedzana yeLDO linear regulators inowanikwa muSOT23-5 uye 1.5-mm × 1.5-mm WSON-6 mapakeji.
