Ukulungisa i-voltage ephumayo nge-LM340

Lesi sifunda esiqondile sisebenzisa i-LM340 ukufezekisa i-voltage ehlukile yokukhipha, eqondiswa yifomula elandelayo:

Ukukhulisa umthamo wamanje we-LM340

Lokhu kucushwa kusekela ukuphuma okulawulwayo kuze kufike ku-5A.I-Q1 ihlala ingasebenzi ngamazinga aphansi aphansi futhi isebenze kuphela lapho okwamanje idlula i-600mA.

Ubukhulu boMlawuli we-LM340

Imininingwane yomenzi

Ama-Texas Amathuluzi, asungulwe ngo-1958, kuholela ekwakheni ubuchwepheshe be-elekthronikhi njengezimoto nemishini yezimboni.Baqasha abantu abangaphezu kuka-30,000 emhlabeni wonke, basebenza ubuchwepheshe obusha owenza amadivaysi asebenze kahle futhi athembeke.Umsebenzi wabo uthuthukisa ukuthi amafektri asebenza kanjani futhi asiza imikhiqizo ehlala isikhathi eside futhi isebenza kangcono.Ama-Texas Amathuluzi aqala ukuhlela ukuqhubeka nokuhlala ensimini yezobuchwepheshe, okwenza babe ngumdlali omkhulu embonini.
