The S3REG10033T28HPCP is a regulator circuit which has been designed to provide 2.5V with a load current of up to 100mA. The output voltage is programmable for minor regulations.
The S3REG10033T28HPCP 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. high-speed ADCs.
The S3REG10033T28HPCP has been designed to allow lowdrop operation (the PMOS pass device has been scaled for a voltage drop of 400mV). To achieve these goals, the S3REG10033T28HPCP requires a 4.7μF external ceramic capacitor.
The S3REG10033T28HPCP 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 trimmable.
The S3REG10033T28HPCP is readily portable to other manufacturing processes or can be customised for specific-Nwell process option.
