The S3REG2533T28HPCP is a regulator circuit which has
been designed to provide 0.9V with a load current of up to
25mA. The output voltage is programmable for minor
The S3REG2533T28HPCP is a regulator circuit that features
an automatic feedback sensing option to maintain a constant
regulated output voltage level. It has been designed to provide
a stable output in both low-drop and high-drop operation, while
maintaining minimum ripple on supply lines in the presence of
large load current spikes inherent with switching loads, e.g.
The S3REG2533T28HPCP has been designed to allow lowdrop
operation (the PMOS pass device has been scaled for a
voltage drop of 450mV). To achieve these goals, the
S3REG2533T28HPCP requires a 4.7μF external ceramic
The S3REG2533T28HPCP uses 2.5V thick oxide devices
from a standard 28nm logic process. The circuit can be scaled
for a range of load currents and the output voltage level is
The S3REG2533T28HPCP is readily portable to other
manufacturing processes or can be customised for specific
-Nwell process option.
