säätötransistoris
Säätötransistori, often translated as control transistor or regulator transistor, refers to a transistor used in an electronic circuit specifically to regulate voltage or current. This means it acts to maintain a stable output level despite variations in the input or load. While many transistor types can be configured for regulation, certain semiconductor devices are designed or commonly employed for this purpose.
The fundamental principle behind a säätötransistori is its ability to vary its resistance based on a control
Commonly used in these applications are bipolar junction transistors (BJTs) and field-effect transistors (FETs). For simpler
