The S3REGC10016T55ULP is a capless regulator circuit which has been designed to provide 0.8-3.0V with a load current of up to mA. 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 S3REGC10016T55ULP 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. pipeline ADCs.
The S3REGC10016T55ULP includes a brownout detection (PGO) which detects when there is a temporary drop in supply voltage.
