Dialog Semiconductor PLC has expanded its configurable mixed-signal IC (CMIC) portfolio with the SLG51000 for advanced camera and sensor systems. Claiming the highest power supply rejection ratio (PSRR) and lowest output voltage noise of any programmable multi-channel LDO regulator on the market, the device provides a PSRR of 73 dB at 1 MHz and output voltage noise of 10 µV (rms).
Meeting tighter noise budgets and exceeding the power performance requirements for applications such as advanced sensor systems or high-end camera modules in smartphones, digital cameras, or other smart imaging devices, the SLG51000 provides an integrated solution that reduces board space. In addition, the configurable output voltage settings, sequencing, and resources can meet multiple project requirements to reduce redesign, sourcing, and qualification time, said Dialog.
Each of the seven channels from the LDO regulator provide from 475-mA to 800-mA output current capability and a low quiescent current of less than 1 µA for the entire IC during shutdown. A variety of functions and control logic such as custom power sequencing, fault signaling, input conditioning, and glue logic can be configured graphically thanks to the IC’s GUI-based development software.
The SLG51000 is sampling now. Production is planned for the second half of 2019.
