sharaxaad gaaban:

LDO-yada waxaa loo kala saaraa inay yihiin LDO-yada wax-soo-saarka togan ama LDO-yada wax-soo-saarka taban.Wax-soo-saarka togan ee LDO-yada (hoos u dhaca) maamulayaasha: isticmaal transistor-ka korantada (sidoo kale loo yaqaan aaladda wareejinta) sida PNP.transistor-kaani waxa uu u ogolaanayaa saturation sidaa darteed maamuluhu waxa uu yeelan karaa danab ka bixitaan aad u hooseeya, sida caadiga ah agagaarka 200mV;LDO-yada wax-soo-saarka taban waxay u isticmaalaan NPN sidii qalabkooda wareejinta waxayna ku shaqeeyaan qaab la mid ah wax-soo-saarka wanaagsan ee LDOs.Wax-soo-saarka taban ee LDO wuxuu u adeegsadaa NPN sidii qalabkiisa wareejinta wuxuuna ku shaqeeyaa qaab la mid ah aaladda PNP ee soosaarka togan ee LDO.

Kala soocidda

Talo Dheeraad ah: Danab ka bixitaanku waa farqiga ugu yar ee u dhexeeya danabka wax-soo-gelinta iyo danab-soo-saarka ee looga baahan yahay maamuleha si uu u ilaaliyo tamarta wax-soo-saarka gudaha 100mV ee ka sarreeya ama ka hooseeya qiimaha magaca.

Doorashada xal

Kobcinta had iyo jeer waa doorasho wanaagsan DCDC, buck, haddii la dooranayo DCDC ama LDO, si loo barbardhigo qiimaha, hufnaanta, buuqa, iyo waxqabadka.

❶ Marka tamarta wax-soo-gelinta iyo wax-soo-saarku ay dhow yihiin, waxaa wanaagsan in la doorto nidaamiyaha LDO, kaasoo gaari kara waxtar aad u sarreeya.

Tusaale: Nidaamiyeyaasha LDO waxaa badanaa loo adeegsadaa codsiyada halka tamarta baytari lithium-ion loo rogo danab wax soo saar 3V ah.Inkasta oo 10% ee ugu dambeeya ee tamarta batteriga aan la isticmaalin, maamulaha LDO wuxuu weli hubinayaa waqti dheer oo batteriga uu shaqeynayo oo leh buuq yar.

❷Marka danabka wax-soo-gelinta iyo danab-soo-saarka aysan aad u dhowayn, sidoo kale tixgeli nooca beddelka DCDC sababtoo ah hadda-gelinta LDO waxay la mid tahay hadda soo-saarka.Haddii hoos u dhaca danabku uu aad u weyn yahay, tamarta lagu isticmaalo LDO aad bay u weyn tahay waxtarkeeduna ma sarreeyo.

Astaamaha xeerbeegtida toosan ee dhaqanka

Nidaamiyeyaasha tooska ah ee caadiga ah: guud ahaan waxay u baahan yihiin tamar-gelinta Uin inay ugu yaraan 2V ~ 3V ka sarreyso tamarta wax soo saarka ee ku saabsan (sida taxanaha 78XX ee chips), haddii kale si sax ah uma shaqeyn doonaan.Laakiin xaaladdan oo kale aad bay u adag tahay.Haddii 5V ilaa 3.3V, farqiga danab ee u dhexeeya gelinta iyo wax soo saarka waa 1.7V oo keliya, kaas oo aan buuxin shuruudaha shaqada ee nidaamiyaha toosan ee caadiga ah.Hoos u dhaca danabkeeda ee nidaamiyaha toosan ee caadiga ah ee isticmaalaya transistor-ka korantada isku xidhka NPN waa ku dhawaad 2V.

Iyada oo la adeegsanayo transistor-ka awoodda MOS waxaa suurtagal ah in la bixiyo tamarta ugu hooseysa.Awoodda MOS, hoos u dhaca korantada ee kaliya ee loo maro xakameynta waxaa sababa iska caabinta ON ee hadda culeyska qalabka korontada.Haddii culeysku yar yahay, hoos u dhaca danab ee habkan ayaa ah kaliya dhowr iyo toban millivolts.
