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. The included over current and
