DESCRIPTION The VB409 VB409SP are fully protected positive voltage regulator designed in STMicroelectronics High Voltage VIPower™ technology.
The devices can be connected directly to the rectified mains (110V/230V).
The devices are well suited for applications powered from the AC mains and requiring a 5V DC regulated output voltage without galvanic insulation.
VB409, VB409SP provides up to 70 mA output current (internally limited) at 5V.
