Product Description

The PL5209M3 series is a group of positive voltage output, three-pin regulators, that provide a

high current even when the input/output voltage differential is small. Low power consumption

and high accuracy is achieved through CMOS and programmable fuse technologies. Output

voltage: 2V to 6V in 0.1V increments.

The PL5209M3 consists of a high-precision voltage reference, an error correction circuit, and a

current limited output driver. Transient response to load variations is improved in comparison

to the existing ones.
