Peb Terminal Voltage Regulators: Taw qhia rau 78L05
Lub 78L05 yog peb lub davhlau ya nyob twg voltage regulator uas yuav siv tau los muab ib tug ruaj khov 5 V tso zis los ntawm ntau yam input qhov chaw. Nws belongs rau cov pab pawg ntawm linear regulators, uas ua hauj lwm los ntawm tsis tu ncua dissipating lub zog tshaj li cua sov.
78L05 yog ib qho kev xaiv nrov rau cov ntawv thov tam sim no nrog nws qhov siab tshaj plaws tso zis tam sim no ntawm 0.1 A. Cov zis hluav taws xob ntawm 5 V yog tsau thiab tuaj yeem siv los siv rau ntau yam khoom siv hluav taws xob, xws li microcontrollers, sensors , los yog LEDs.
Qhov siab tshaj plaws tag nrho dissipation rau 78L05 yog 0.625 W ntawm qhov kub thiab txias ntawm 25 degree, uas txiav txim siab npaum li cas lub hwj chim ntawm regulator yuav lis tsis overheating. Txhawm rau kom tus tswj hwm hauv nws qhov kev nyab xeeb kev ua haujlwm, lub heatsink tuaj yeem ntxiv los pab kom cov cua sov ntau dhau.
Lub 78L05 tuaj nyob rau hauv ib lub me me, peb-pin TO-92 pob uas ua rau nws yooj yim rau siv ntawm lub breadboard los yog nyob rau hauv ib tug me me Circuit Court. Nws ua haujlwm ntawm qhov dav input voltage ntau ntawm 7V txog 35V, ua rau nws haum rau ntau yam kev siv.
Ib qho txiaj ntsig tseem ceeb ntawm kev siv hluav taws xob tswj hluav taws xob xws li 78L05 yog tias nws muab qhov tso zis hluav taws xob ruaj khov txawm tias qhov hluav taws xob nkag tsis tas li. Qhov no yog qhov tseem ceeb rau kev ua kom ntseeg tau tias cov khoom siv hluav taws xob siv hluav taws xob ua haujlwm kom raug thiab tsis raug kev txom nyem los ntawm kev hloov hluav taws xob.
78L05 yog ib qho kev txhim khu kev qha thiab ntau yam peb lub davhlau ya nyob twg voltage regulator uas feem ntau siv rau hauv cov ntawv thov tam sim no. Nws qhov me me, qhov ntau qhov hluav taws xob ntau qhov hluav taws xob, thiab cov zis hluav taws xob ruaj khov ua rau nws muaj kev xaiv nrov rau cov neeg nyiam ua haujlwm hauv hluav taws xob, cov tub ntxhais kawm, thiab cov kws tshaj lij.
