BC557 is a PNP transistor hence the collector and emitter will be closed Forward biased when the base pin is held at ground and will be opened Reverse biased when a signal is provided to base pin. Transistor menjadi komponen aktif yang utama di semua rangkaian elektronik. 018 g C B E Plastic material has UL classification 94V-0 Gehusematerial. BC548549 80 50 30 V V V VCEO Collector-Emitter Voltage. Program persamaan komponen transistor datasheet IC juga disediakan.

Untuk TV Slim biasa pake transistor horisontal tanpa dioda sebab sudah ada dioda dampernya. Transistor umumnya dibuat dari bahan silikon dan sebagian terutama transistor-transistor. 4112018 BC557 Transistor Explained Description.

PS: SOLVED!! My mistake, I connected a NPN BJT instead of PNP.Untuk mengunduh File Gunakan tombol download dibawah ini.

The only thing I had to work with was the datasheet. I want this circuit to work, and I also want to understand this circuit further so if you could point me to other learning material concerning this circuit then that would be great. I already have a switching regulator and I also have a higher current linear regulator so don't suggest them please.

The LM7812 works great when no series pass transistor is attached. While calculating R1 I assumed the value for Ireg to be 0.1A, Beta of transistor to be ~95, and IQ1 to be 3A, when that didn't work I tried a bunch of different values of resistors with the same results. Is the output voltage affected by the the value of R1? I tried different values of R1 calculated by the formula shown in the data sheet.

It just showed ~2V less then the input voltage.Īt 18V no load I got 16V output, 0.5A load 15V and 3A load 12V. Simulate this circuit – Schematic created using CircuitLabīut as I connected it to my bench power supply set to 18V I was not able to get a regulated output. I made the same circuit as shown in the datasheet and used the 2SD1047 as Q1 I want to build a regulator using 7812 with series pass transistor for higher current as shown in the datasheet, page 20.

The amplifier draws over 3 amps on full load. I already have a switching regulator for most application but it is very noisy for amplifier even with a lot of filtering. I am making a 12 volt regulator for a solar panel to power an audio amplifier.
