APPLICATIONS INFORMATION
The LT1083 family of three-terminal adjustable regulators is easy to use and has all the protection features that are expected in high performance voltage regulators. They are short-circuit protected, and have safe area protection as
well as thermal shutdown to turn off the regulator should the junction temperature exceed about 165C. These regulators are pin compatible with older threeterminal adjustable devices, offer lower dropout voltage and more precise reference tolerance. Further, the reference stability with temperature is improved over older types of regulators. The only circuit difference between using the LT1083 family and older regulators is that this new family requires an output capacitor for stability.
Stability
The circuit design used in the LT1083 family requires the use of an output capacitor as part of the device frequency compensation. For all operating conditions, the addition of 150μF aluminium electrolytic or a 22μF solid tantalum on the output will ensure stability. Normally, capacitors much smaller than this can be used with the LT1083. Many different types of capacitors with widely varying characteristics are available. These capacitors differ in capacitor tolerance (sometimes ranging up to +/-100%), equivalent series resistance, and capacitance temperature coefficient. The 150μF or 22μF values given will ensure stability.
When the adjustment terminal is bypassed to improve the ripple rejection, the requirement for an output capacitor increases. The value of 22μF tantalum or 150μF aluminum covers all cases of bypassing the adjustment terminal. Without bypassing the adjustment terminal, smaller capacitors can be used with equally good results and the table below shows approximately what size capacitors are needed to ensure stability.
As a successor of HIFIER series, Fans Digital March was designed for those users who use HTPC and enjoy HIFI audio. No doubt, it is excellent on the way perfect sound chasing.
Pure digital and high quality oscillators ensure the most precise digital clock. Besides, we use OS-CON capacitors in the electric power circuit to assure it is clean enough of electric current Digital March uses. 3 different types of connector for user connect other equipments more easily.
Not only supporting the existing digital equipments, Digital March also features internal S/PDIF output connector for transferring S/PDIF signal to those display cards which with HDMI encoder. Thats all? No, there are some surprises for you to find out yourself.

อันนี้เป็นอีกแบบ แบบ full-wave center tap rectifier ใช้ C ฟิลเตอร์ของ Jensen 4 Pole ตัวใหญ่ 15,000uF/63v ตัวเล็ก 47,000uF/25v ทำไมมันใช้ค่าเยอะจังครับ...
ผมดูแล้วและตามที่ผมเข้าใจ 12v ที่P4 จ่ายให้ cpu กับ 5v ที่P24 จ่ายให้เมนบอร์ด น่าจะสำคัญสุด ก็เลยหาข้อมูลเรื่อง C ไปเรื่อย... เห็น C ของ Mundorf ที่เป็นแบบ M -Lytic Audio Grade Power Cap น่าสนใจ... ลองเอามาใช้ตรง C ฟิลเตอร์ ตรงสองจุดนี้ คุณ keang ว่ามันจะเข้าท่าเปล่าครับ แล้วมันแพงไปหรือเปล่าครับ หรือพอๆกับยี้ห้ออื่นที่ดีๆหน่อยที่เขานิยมกันครับ... http://www.supremecap.net/capacitors.html
