® VB409 / VB409SP HIGH VOLTAGE REGULATOR POWER I.C. PRELIMINARY DATA TYPE VB409 VB409SP ICL(in) 0.8 A ICL(out) 70 mA VOUT 5V ± 5% s s s s s s NO HIGH VOLTAGE EXTERNAL CAPACITOR 5 V DC REGULATED OUTPUT VOLTAGE OUTPUT CURRENT LIMITED TO 70 mA THERMAL SHUT-DOWN PROTECTION INPUT OVERCURRENT PROTECTION POWER DISSIPATION INTERNALLY LIMITED 10 1 PENTAWATT HV(022Y) PowerSO-10™ 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 BLOCK DIAGRAM ORDER CODES: PENTAWATT HV(022Y) VB409 PowerSO-10™ VB409SP thermal shutdown provide protection for the device.
