The S3REG5033TJ180 is a regulator circuit which has been designed to provide 1.8V with a load current of up to 50mA, having a low area and high PSRR.
The S3REG5033TJ180 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. pipeline ADCs.
The S3REG5033TJ180 has been designed to allow low-drop operation in a low area (the PMOS pass device has been scaled for a voltage drop of 500mV). To achieve these goals, the S3REG5033TJ180 requires a 1μF external ceramic capacitor.
