Salam, mungkin sebagai alternarip bisa coba LM338 utk regulated psu. Blessings,

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...

Pertanyaan LM317, coba di lihat datasheet-nya. .. salam, dwa ----- Original Message ----- From: Yustinus To: ELPOP-Audio@ yahoogroups. com Sent: Monday, November 17, 2008 11:02 AM Subject: [ELPOP-Audio] nanya 7805 & 7806, trus 317 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 ************ ********* ********* ********* ********* ********* ********* This message originated from the Internet.
