The VB409, VB409SP, VB409(022Y) are fully protected positive voltage regulators designed in STMicroelectronics High Voltage VIPower™ M1-2 technology. The devices can be connecteddirectly to the rectified mains. They are well suited for applications powered from the AC mains and requiring a 5V DC regulated output and/or max 16V not regulated output voltages without galvanic insulation. VB409, VB409SP, VB409(022Y) provide up to 80 mA minimum output current (internally limited) at 5V. The included over current and thermal shutdown provide protections for the device.
