Low Drop Out 1mA Capless Regulator

The Low Drop Out Regulator is a voltage regulator circuit which has been designed to provide 1.18-1.24V with a load current of up to 1.3 mA, having a low area and high accuracy.

The Low Drop Out Regulator does not require an external capacitor. The regulator’s architecture has been designed so that is stable without such an external capacitor, yet yielding a small area while consuming low ground current allowing low-drop operation.

The Low Drop Out Regulator uses 3.3V thick oxide devices from a standard 65nm LPe process. The circuit can be scaled for a range of load currents and capacitances.

As no external capacitor is needed, the Low Drop Out Regulator capless regulator can provide savings in terms of package pins and discrete capacitors, allowing reduced BOM costs and higher system reliability. It can be particularly useful if the IC design is ‘pad limited’.

The Low Drop Out Regulator is readily portable to any similar manufacturing process or can be customised for specific customer requirements and it’s designed with Deep-NWell process option.
