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

thermal shutdown provide protection for the

device.
