US Patent Issued to Cypress Semiconductor on Sept. 9 for "Low-power fast-transient low-dropout (LDO) regulator with direct feed-forward" (Texas Inventor)

ALEXANDRIA, Va., Sept. 10 -- United States Patent no. 12,411,510, issued on Sept. 9, was assigned to Cypress Semiconductor Corp. (San Jose, Calif.).

"Low-power fast-transient low-dropout (LDO) regulator with direct feed-forward" was invented by Adrian Lin (Austin, Texas).

According to the abstract* released by the U.S. Patent & Trademark Office: "A low-dropout (LDO) regulator includes a voltage reference node and a one-stage differential amplifier coupled to the voltage reference node. The one-stage differential amplifier includes: a differential pair of NMOS transistors; a mirroring load comprising a first current source and a PMOS transistor; a direct feed-forward (DFF) loop formed by the PMOS transistor and its parasitic gate-to-drain ...
