The RY6050-ADJM5R is a SOT-23-5 linear voltage regulator manufactured by RYCHIP and is ROHS compliant. It is rated at 500mA with a maximum of 70dB at 100Hz. The regulator is adjustable and is designed for positive 6.5V output. It is a low-dropout (LDO) type regulator, which means that the input voltage must be higher than the output voltage by 1V or more. It is an excellent choice for battery-powered applications.
