This power supply is ideal for power up your embedded systems. I have been used this power supply with my electronic projects. This regulator has the capability of delivering 1 A continues current. The IC has very low power dissipation and no need of external heat sink for most applications. The copper pour on your PCB or ground PCB layer is enough to dissipate the heat to environment. It is recommend to use this power supply for PIC microcontrollers, Atmal AVR, ARM and all 5 V embedded systems which utilizes current less than 1A.
The voltage regulation is extremely good in design and you may obtain the best performances of the regulator with low ESR capacitor (C3).

The IC has an remote shutdown facility that can be use to power saving applications.
Important : Make sure to use good ferrite core inductor.
