... REFEN APPLICATION INFORMATION Input Capacitor and Layout Consideration Place the input bypass capacitor as close as possible to the AP1270. A low ESR capacitor larger than 470uF is recommended for the input capacitor. Use short and wide traces to minimize parasitic resistance and inductance. Inappropriate layout may result in large parasitic inductance and cause undesired oscillation between AP1270 and the preceding powe converter ...

... There are two reasons doing this design; one is for output voltage soft-start while another is for noise immunity. Thermal Consideration AP1270MP regulators have internal thermal limiting circuitry designed to protect the device during overload conditions.For continued operation, do not exceed maximum operation junction o temperature 125 C ...
