The Low Drop Out Regulator has been designed to provide 1.2V with a load current of up to 250mA. The output voltage is programmable.
The Low Drop Out Regulator 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 Low Drop Out Regulator 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 Low Drop Out Regulator requires a 4.7ƒÝF external ceramic capacitor.
The Low Drop Out Regulator uses 2.5V thick oxide devices from a standard 65nm logic process. The circuit can be scaled for a range of load currents and the output voltage level is programmable.
For maximum flexibility, the user can adjust the regulated output voltage if the Low Drop Out Regulator is placed on a different chip.
The Low Drop Out Regulator is readily portable to other manufacturing processes or can be customised for specific customer requirements and it's designed with the Deep-Nwell process option.
