07:51200mA LDO regulators
Toshiba Electronics Europe has expanded its family of low drop out (LDO) voltage regulators with a series of CMOS devices. Available with output voltages from 1.5V to 5.0V, devices in this LDO regulator family (TCR5SBxx series) deliver a maximum output current of 200mA and are supplied in a SOT25 (SMV) package. The LDO regulators have a typical quiescent current of 40µA and a dropout voltage of 85mV (at 50mA). The ripple rejection (RR) of 80dB at 1kHz is independent of output voltage.
This makes the LDO especially suitable for power supply applications that are very sensitive to variations in supply voltage (e.g. RFICs). Additionally, without external noise bypass capacitors an ultra-low output noise voltage (VNO) rating of 30µVrms - independent of output current - is achieved. The regulators are dedicated for power supply solutions in Bluetooth devices, cameras, personal audio players, mobile phones and other portable and handheld battery-powered applications. All products in the TCR5SBxx series offer an on/off control function and built in overcurrent protection.

07:50Certified USB 2.0 PHY IP for 45 nm process
Synopsys announced that its DesignWare USB 2.0 nanoPHY is the first 45-nanometer USB 2.0 PHY intellectual property (IP) to successfully pass the USB Implementers Forum Hi-Speed USB PHY certification. Synopsys' USB 2.0 nanoPHY mixed-signal IP, now available in the 45-nm process node, uses half the power and die area compared to previous USB PHY IP solutions and enables faster time-to-market with reduced risk. The DesignWare USB 2.0 nanoPHY IP is targeted for a broad range of high-volume, mobile and consumer applications. In addition, the DesignWare USB 2.0 nanoPHY IP has built-in tuning circuits that enable post-silicon adjustments to account for unexpected chip/board parasitics or process variations without the need to modify the existing design.
The DesignWare USB 2.0 nanoPHY is part of the complete USB 2.0 IP solution from Synopsys, which includes the USB 2.0 digital controllers, PHY and verification IP. Synopsys offers a comprehensive portfolio of USB IP for 180-nm, 130-nm, 90-nm, 65-nm and now 45-nm process technologies. The logo-certified nanoPHY IP is available now.
In addition, the USB 2.0 nanoPHY for the 40-nm process is currently scheduled to be available in the second half of 2008. The complete DesignWare USB 2.0 solution, including the PHY IP (ranging from 180-nm to 45-nm), digital controllers and verification IP are also available today.
