Description

The NCP566 low dropout (LDO) linear voltage regulator will provide 1.5 A at a fixed output voltage. The fast loop response and low dropout voltage make this regulator ideal for applications where low voltage and good load transient response are important. Device protection includes current limit, short circuit protection, and thermal shutdown. The NCP566 is packaged in a SOT-223.
