Yang saya tahu sih Kang Yus (which is ngga banyak juga)

7805 regulate at fixed output voltage of 5V, hence the last two number.
Yang 7806 yah yang 6V outputnya. Jadi bedanya apa? pak didik bilang yah 1
volt hehehe

Kalo LM 317 itu output voltagenya variable (lupa saya rangenya)... caranya
pake nilai resistor yang berbeda2 (atau pake trimpot aja) sambil diukur
voltage out dengan multimeter gitu...

bagus mana? wah kayaknya sih sama aja... soalnya ini semuanya tergulang ber
ampere kecil (mesti dobel2 makenya kalo buat power amp). Kalo mo oke ada
tuh IC yang LTberapa gitu yang bisa 8 Ampere kalo ngga salah.. cuma
harganya euy!!!

Kalo beda voltage in ama out sih sebenarnya 3v juga udah ok (ga perlu
heatsink malahan... mungkin)... tapi amannya mungkin 4-5V kali yah... cuma
mesti pake heatsink... soalnya prinsip kerjanya IC voltage regulator ini
dengan merubah excess voltage menjadi panas...

Thanks and regards,
Fajar

Kang Yus,

7805 dan 7806....., bedanya 1V ! :D.
Pertanyaan LM317, coba di lihat datasheet-nya. ..

dear friends,

nah sekarang giliran saya yang bertanya bodoh.
Kalau ic regulator 7805 dan 7806 bedanya apa ya?
Bagus mana dibanding LM317?

Apakah LM317 hanya keluaran National? Kemaren sempat beli LM317 tapi
bukan Natsemi, ST kalo ga salah. Ada perbedaan kualitaskah?

Berapa beda tegangan optimal antara in dan out di LM317 supaya
hasilnya baik?

makasih banyak sebelumnya.

thanks.
yus
