Linear regulator

Muzamagetsi, mzere wowongolera ndi avoltage regulatoramagwiritsidwa ntchito kuti magetsi azikhala okhazikika.[1]Kukaniza kwa regulator kumasiyanasiyana malinga ndi magetsi olowera ndi katundu, zomwe zimapangitsa kuti pakhale kutulutsa kwamagetsi kosalekeza.Dera lowongolera limasiyanasiyanakukaniza, kusintha mosalekeza avoteji dividernetiweki kusunga voteji mosalekeza linanena bungwe ndi mosalekeza dissipating kusiyana athandizira ndi malamulo voteji mongakutaya kutentha.Mosiyana, aswitching regulatoramagwiritsa ntchito chipangizo chomwe chimayatsa ndi kuzimitsa (oscilates) kuti chikhale ndi mtengo wapakati pazotulutsa.Chifukwa voteji yoyendetsedwa ndi chowongolera chowongolera nthawi zonse imayenera kukhala yotsika kuposa voliyumu yolowera, mphamvuyo imakhala yochepa ndipo magetsi olowera ayenera kukhala okwera mokwanira kuti nthawi zonse chida chogwira chigwetse magetsi.

Owongolera ma Linear amatha kuyika chipangizo chowongolera kuti chifanane ndi katundu (shuntchowongolera) kapena akhoza kuyika chipangizo chowongolera pakati pa gwero ndi katundu woyendetsedwa (zowongolera mndandanda).Zowongolera zama mzere wosavuta zitha kukhala ndi zochepa ngati aZener diodendi resistor mndandanda;zowongolera zovuta kwambiri zimaphatikizapo magawo osiyana a referensi yamagetsi, amplifier zolakwika ndi chinthu chodutsa mphamvu.Chifukwa mzerevoltage regulatorndi chinthu chofala pazida zambiri, zowongolera za single-chipICsndizofala kwambiri.Ma Linear regulators amathanso kupangidwa ndi magulu a discrete solid-state kapenavacuum chubuzigawo.

Ngakhale dzina lawo, owongolera mizere alizozungulira zopanda mzerechifukwa ali ndi zigawo zopanda mzere (monga ma diode a Zener, monga momwe tawonetsera pansipayosavuta shunt regulator) ndipo chifukwa voteji yomwe imatulutsa imakhala yosasinthasintha (ndipo dera lomwe limatulutsa nthawi zonse lomwe silidalira zomwe limalowetsa ndi dera lopanda mzere.)[2]

Chithunzi cha TLV702

Zowongolera zamtundu wa TLV702 za low-dropout (LDO) ndi zida zotsika zomwe zili ndi mizere yabwino kwambiri komanso magwiridwe antchito osakhalitsa.Ma LDO awa adapangidwa kuti azigwiritsidwa ntchito movutikira mphamvu.Bandgap yolondola komanso amplifier yolakwika imapereka kulondola kwa 2%.Phokoso lotsika kwambiri, chiŵerengero champhamvu kwambiri cha kukana mphamvu (PSRR), ndi magetsi otsika kwambiri amachititsa kuti zipangizozi zikhale zabwino kwambiri pazida zambiri zogwiritsira ntchito batire.Mitundu yonse yazida ili ndi kuzima kwa kutentha komanso malire apano achitetezo.

Kuphatikiza apo, zida izi ndizokhazikika komanso mphamvu zotulutsa za 0.1 µF zokha.Izi zimathandizira kugwiritsa ntchito ma capacitor otsika mtengo omwe ali ndi ma voltages apamwamba komanso kutsika kwa kutentha.Zipangizozi zimayang'anira kulondola kotchulidwa popanda kutulutsa katundu.

Mndandanda wa TLV702P umaperekanso mayendedwe othamanga kuti atulutse zotulukapo mwachangu.

Mndandanda wa TLV702 wa LDO linear regulators akupezeka mu SOT23-5 ndi 1.5-mm × 1.5-mm WSON-6 phukusi.
