==Scalable Low Dropout Regulator - A simplified explanation of the abstract==


This abstract first appeared for US patent application 17806908 titled 'Scalable Low Dropout Regulator

==Simplified Explanation==

The patent application describes a regulator circuit for a computer system that adjusts the conductance values between an input power supply node and a regulated power supply node. This is done by using a control circuit and multiple pass circuits. The number of pass circuits can be adjusted based on a threshold load current or a threshold conductance.

* The regulator circuit includes a control circuit and multiple pass circuits.
* The pass circuits adjust the conductance values between the input power supply node and the regulated power supply node.
* The number of pass circuits can be adjusted based on a threshold load current or a threshold conductance.
* The control circuit uses sense currents, a reference voltage, and the voltage level of the regulated power supply node to adjust the conductance values.

Potential applications of this technology:

* Computer systems
* Electronic devices
* Power supply systems

Problems solved by this technology:

* Efficiently regulating power supply in computer systems and electronic devices
* Adjusting conductance values based on load current or conductance thresholds

Benefits of this technology:

* Improved power regulation in computer systems and electronic devices
* Flexibility to adjust the number of pass circuits based on specific requirements
* Efficient use of power supply resources


==Original Abstract Submitted==

A regulator circuit included in a computer system may include a control circuit and multiple pass circuits that source respective supply currents to a regulated power supply node by adjusting respective conductance values between an input power supply node and the regulated power supply node. The number of pass circuits can be adjusted on a design-by-design basis based on a threshold load current for the regulator circuit or on a threshold conductance between the input power supply node and the regulated power supply node. The control circuit adjusts the respective conductance values using a combination of respective sense currents generated by the multiple pass circuits along with a reference voltage and a voltage level of the regulated power supply node.
