The S3REG10016T40LP is a regulator circuit which has been designed to provide 0.90-2.8V with a load current of up to 100mA. The output voltage is programmable.
The S3REG10016T40LP 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 S3REG10016T40LP has been designed to allow low-drop operation (the PMOS pass device has been scaled for a voltage drop of 350mV). To achieve these goals, the S3REG10016T40LP requires a 4.7 F external ceramic capacitor.
The S3REG10016T40LP uses 2.5V thick oxide devices from a standard 40nm logic process. The circuit can be scaled for a range of load currents and the output voltage level is programmable.
