... Supertex inc. Adjustable Off-Line General Description The Supertex SR086 is an inductorless switching regulator designed to operate directly from a rectified AC line. The operating principle is to turn on a pass transistor when the rectifi below the output voltage, and to turn it off when the output voltage reaches a specific level. A linear regulator supplied by V 3.3V output. Effi ...
