The LP5907 is a low-nose, high PSSR, ultra-low dropout voltage regulator from TI. It is capable of delivering output current up to 250mA. The LP5907 also feature low quiescent current and low line and load transient response figures.
APDS-9930 is a digital ambient light and proximity sensor. Developed for use in a variety of applications, this compact module combines an infrared LED with a photodetector to measure the light reflected back from nearby objects, thereby determining their proximity.
