Input Decoupling Capacitor (C1)
connected as close as possible to the input and ground pin of
the NCP4620. Higher values and lower ESR improves line
transient response.
Output Decoupling Capacitor (C2)
achieve stable operation of the IC. If a tantalum capacitor is
used, and its ESR is high, loop oscillation may result. The
capacitors should be connected as close as possible to the
output and ground pins. Larger values and lower ESR
improves dynamic parameters.

Enable Operation
on and off. The IC is switched on when a high level voltage
is applied to the CE pin. The enable pin has an internal pull
down current source. If the enable function is not needed
connect CE pin to VIN.
Output Discharger
GND that is used for faster discharging of the output
capacitor. This function is activated when the IC goes into
disable mode.
Thermal
necessary to provide some thermal relief. The maximum
power dissipation supported by the device is dependent
upon board design and layout. Mounting pad configuration
on the PCB, the board material, and also the ambient
temperature affect the rate of temperature increase for the
part. When the device has good thermal conductivity
through the PCB the junction temperature will be relatively
low in high power dissipation applications.
PCB layout
impedance is high, noise pickup or unstable operation may
result. Connect capacitors C1 and C2 as close as possible to
the IC, and make wiring as short as possible.
The enable pin CE may be used for turning the regulator
