The Fuman 65K5 with Dropout Regulators (LDO) SOT23-3 RoHS is a device used to regulate the output voltage of a system while protecting it from large voltage drops and containing conditions. It is a low-dropout linear regulator, which provides a constant output voltage of 5V while dissipating only a small amount of power. The SOT23-3 RoHS packaging provides a low profile, making it suitable for small PCBs. The device has excellent thermal characteristics, allowing it to be used in various applications, such as computers, modems, and communication devices. It is manufactured in accordance with the RoHS directive and is compliant with environmental regulations.
