The S3REGC5016T40LP is a capless regulator circuit which has been designed to provide 0.8-3.0V with a load current of up to 50mA. The output voltage is programmable in 100mV steps.
No external capacitor is required; the regulator’s architecture has been designed so that it is stable without such an external capacitor, yet yielding a small area while consuming low ground current and allowing low-drop operation.
The S3REGC5016T40LP 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 prsence of large load current spikes inherent with switching loads, e.g. pipeline ADCs.
The S3REGC5016T40LP uses 2.5V thick oxide devices from a standard 40nm logic process. The circuit can be scaled for a range of load currents and capacitances.
