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
