LOW-DROPOUT (LDO) REGULATOR WITH A FEEDBACK CIRCUIT - A simplified explanation of the abstract
This abstract first appeared for US patent application 17877115 titled 'LOW-DROPOUT (LDO) REGULATOR WITH A FEEDBACK CIRCUIT
Simplified Explanation
The abstract describes a voltage regulator circuit that includes a voltage regulator, a connector, a plurality of macros, and a feedback circuit. The voltage regulator is responsible for providing an output voltage at an output terminal. The connector is connected to the output terminal of the voltage regulator and allows for the connection of multiple macros. The feedback circuit, which consists of multiple feedback loops, is also connectable to the connection nodes of the connector. Each feedback loop, when connected to a connection node, provides the instantaneous voltage of that node as feedback to the voltage regulator. The voltage regulator then adjusts the output voltage based on this feedback to maintain the instantaneous voltage of the connection node close to a reference voltage.
- The voltage regulator circuit regulates the output voltage to keep the instantaneous voltage of the connection node approximately equal to a reference voltage.
- The circuit includes a connector that allows for the connection of multiple macros to the output terminal of the voltage regulator.
- The feedback circuit consists of multiple feedback loops that provide the instantaneous voltage of each connection node as feedback to the voltage regulator.
- The voltage regulator adjusts the output voltage based on the feedback received from the feedback circuit.
Potential applications of this technology:
- Power supply systems: The voltage regulator circuit can be used in various power supply systems to regulate the output voltage and maintain stability.
- Electronic devices: This circuit can be integrated into electronic devices to ensure a stable and regulated power supply for their components.
- Renewable energy systems: The voltage regulator circuit can be utilized in renewable energy systems, such as solar or wind power systems, to regulate the output voltage and optimize energy conversion.
Problems solved by this technology:
- Voltage regulation: The circuit solves the problem of maintaining a stable and regulated output voltage, even when multiple macros are connected to the output terminal.
