The NCP605/NCP606 provide in excess of 500 mA of output

current at fixed voltage options or an adjustable output voltage from

5.0 V down to 1.25 V. These devices are designed for space

constrained and portable battery powered applications and offer

additional features such as high PSRR, low noise operation, short

circuit and thermal protection. The devices are designed to be used

with low cost ceramic capacitors and are packaged in the DFN6 3x3.3.

NCP605 is designed without enable pin, NCP606 is designed with

enable pin.
