说明
- TIDA-00718, Small Size, Low Noise and High PSRR Power Reference Design for CMOS Image Sensors. The TIDA-00718 reference design provides a small size and high input voltage ripple rejection power supply to provide a stable and clean voltage source for CMOS image sensors. In this design a main power rail of 5V from battery, Power over Ethernet (PoE) or DC adaptor is regulated down to three voltage rails: 3.3V, 1.8V and 1.2V. This solution can be utilized in consumer electronics and commercial applications as IP Network Cameras, Analog Security Camera, Video Doorbell, Internet webcam and many more
