Low-Dropout Regulator Circuit with Dynamic Transition Between Operation Modes - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240094753 titled 'Low-Dropout Regulator Circuit with Dynamic Transition Between Operation Modes
Simplified Explanation
The patent application describes a low-dropout (LDO) regulator circuit that can dynamically transition between two operation modes based on a switch mode enable signal. In the first mode, the output voltage depends on a reference voltage, while in the second mode, the output voltage is independent of the reference voltage.
- Operational amplifier with a reference voltage input and a feedback circuit connected to the output
- Pass transistor selectively coupled to the feedback circuit and the output via switches controlled by a switch mode enable signal
- Transition between operation modes based on changes in the switch mode enable signal

Unanswered Questions
How does the transition between operation modes impact the overall efficiency of the regulator circuit?
The transition between operation modes may introduce some switching losses, but the overall efficiency could be optimized through proper design and control strategies.
What are the key factors influencing the selection of the reference voltage for the regulator circuit?
The selection of the reference voltage may depend on the desired output voltage range, system requirements, and stability considerations.
Original Abstract Submitted
a low-dropout (ldo) regulator circuit with dynamic transitioning between first and second operation modes. the ldo regulator circuit includes an operational amplifier with a first input connected to a reference voltage, a feedback circuit connected between a second input of the operational amplifier and an output of the ldo regulator circuit, and a pass transistor selectively coupled to the feedback circuit and an output of the operational amplifier via a set switches controlled by a switch mode enable signal. the ldo regulator circuit transitions between the first and second operation modes responsive to one or more changes of the switch mode enable signal. in the first operation mode, a load voltage at the output of the ldo regulator circuit has a first voltage value that depends on the reference voltage. in the second operation mode, the load voltage has a second voltage value independent from the reference voltage.
