Linear regulator
Muzamagetsi,amzere wowongolerandi 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 LP5912-Q1
LP5912-Q1 ndi LDO yaphokoso yotsika yomwe imatha kupereka mpaka 500 mA yotulutsa pano.Chopangidwa kuti chikwaniritse zofunikira za RF ndi ma analogi mabwalo, chipangizo cha LP5912-Q1 chimapereka phokoso lochepa, PSRR yapamwamba, yotsika kwambiri, komanso mizere yotsika komanso kuyankha kwakanthawi kochepa.LP5912-Q1 imapereka phokoso lotsogola m'kalasi popanda phokoso lodutsa capacitor komanso kuthekera koyika patali.
Chipangizocho chimapangidwa kuti chizigwira ntchito ndi cholowetsa cha 1-µF ndi 1-µF chotulutsa ceramic capacitor (palibe cholumikizira chaphokoso chosiyana chofunikira).
Chipangizochi chimapezeka ndi ma voltages okhazikika kuchokera ku 0,8 V mpaka 5.5 V mumayendedwe a 25-mV.Lumikizanani ndi Texas Instruments Sales kuti mupeze zofunikira zina zamagetsi.
Pamaphukusi onse omwe alipo, onani Package Option Addendum (POA) kumapeto kwa pepalali.
