Linear regulator
Hauvhluav taws xob, alinear regulatoryog 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]

Nqe lus piav qhia rau LP5912-Q1
LP5912-Q1 yog lub suab qis LDO uas tuaj yeem muab tau txog 500 mA ntawm cov zis tam sim no.Tsim los ua kom tau raws li qhov yuav tsum tau muaj ntawm RF thiab analog circuits, LP5912-Q1 ntaus ntawv muab lub suab qis, siab PSRR, tsis tshua muaj suab nrov tam sim no, thiab cov kab qis thiab cov lus teb ib ntus.LP5912-Q1 muaj cov suab nrov hauv chav kawm uas tsis muaj lub suab nrov bypass capacitor thiab nrog lub peev xwm rau cov chaw taws teeb tso zis.
Cov cuab yeej tsim los ua haujlwm nrog 1-µF cov tswv yim thiab 1-µF tso tawm ceramic capacitor (tsis muaj suab nrov bypass capacitor xav tau).
Cov cuab yeej no muaj nyob nrog cov zis hluav taws xob tas li ntawm 0.8 V rau 5.5 V hauv 25-mV cov kauj ruam.Hu rau Texas Instruments Muag rau cov kev xav tau tshwj xeeb voltage xaiv.
