Linear regulator

Hauvhluav taws xob, linear regulator yog avoltage regulatorsiv los tuav lub zog ruaj khov.[1]Qhov tsis kam ntawm tus regulator sib txawv raws li ob qho tib si input voltage thiab load, uas ua rau ib tug tas li voltage tso zis.Lub regulating circuit nws txawvtsis kam, tsis tu ncua kho avoltage dividernetwork tswj kom muaj qhov tso zis tsis tu ncua thiab txuas ntxiv dissipating qhov sib txawv ntawm cov tswv yim thiab tswj cov voltages raws likhib kub.Los ntawm qhov sib txawv, ahloov regulatorsiv cov cuab yeej nquag uas hloov mus rau thiab tawm (oscilates) kom tswj tau qhov txiaj ntsig nruab nrab ntawm cov zis.Vim tias qhov kev tswj hwm qhov hluav taws xob ntawm cov kab hluav taws xob yuav tsum ib txwm qis dua qhov hluav taws xob tawm tswv yim, kev ua haujlwm raug txwv thiab cov khoom siv hluav taws xob yuav tsum siab txaus kom ib txwm tso cai rau cov cuab yeej ua haujlwm kom poob qee qhov hluav taws xob.

Linear regulators tuaj yeem tso cov cuab yeej tswj kev sib txuas nrog cov khoom thauj (shuntregulator) los yog tej zaum yuav tso lub regulating ntaus ntawv ntawm qhov chaw thiab cov regulated load (ib tug series regulator).Tej yam yooj yim linear regulators yuav tsuas muaj tsawg li ibZener diodethiab series resistor;Ntau cov regulators nyuaj muaj xws li cais theem ntawm kev siv voltage, yuam kev amplifier thiab lub zog dhau lub caij.Vim yog linearvoltage regulatoryog ib qho khoom siv ntawm ntau yam khoom siv, ib leeg-chip regulatorsICsmuaj ntau heev.Linear regulators kuj tseem tuaj yeem tsim los ntawm kev sib dhos ntawm cov khoom sib cais-lub xeev lossislub tshuab nqus tsevcov khoom.

Txawm tias lawv lub npe, linear regulators yogtsis-linear circuitsvim tias lawv muaj cov khoom tsis-linear (xws li Zener diodes, raws li qhia hauv qab no hauvyooj yim shunt regulator) thiab vim hais tias qhov tso zis hluav taws xob yog qhov zoo li qub (thiab ib lub voj voog nrog cov zis tas li uas tsis nyob ntawm nws cov tswv yim yog qhov tsis yog-linear circuit.)[2]

Kev piav qhia rau TLV702

TLV702 series ntawm low-dropout (LDO) linear regulators yog cov khoom siv tsis tshua muaj quiescent tam sim no nrog cov kab zoo heev thiab kev thauj mus los ntev.Cov LDOs no yog tsim los rau kev siv lub zog-sensitive.A precision bandgap thiab yuam kev amplifier muab tag nrho 2% raug.Tsis tshua muaj suab nrov, siab zog-supply rejection ratio (PSRR), thiab low-dropout voltage ua no series ntawm cov cuab yeej zoo tagnrho rau ib tug dav xaiv ntawm cov khoom siv tes ua roj teeb.Tag nrho cov cuab yeej siv tau muaj thermal kaw thiab tam sim no txwv rau kev nyab xeeb.

Tsis tas li ntawd, cov cuab yeej no ruaj khov nrog cov txiaj ntsig zoo ntawm qhov tsuas yog 0.1 µF.Qhov no tso cai rau siv cov nqi-zoo capacitors uas muaj ntau dua kev tsis ncaj ncees voltages thiab kub derating.Cov cuab yeej tswj xyuas qhov tseeb uas tsis muaj qhov tso zis tawm.

TLV702P series kuj tseem muab lub zog rub tawm kom nrawm nrawm rau cov khoom tawm.

TLV702 series ntawm LDO linear regulators muaj nyob rau hauv SOT23-5 thiab 1.5-mm × 1.5-mm WSON-6 pob.
