Linear low-dropout (LDO) regulators are not a specific brand but a category of voltage regulators used in electronics. They are produced by various companies worldwide, including Analog Devices (USA), Texas Instruments (USA), STMicroelectronics (Switzerland), and ON Semiconductor (USA). These regulators serve industries like consumer electronics, automotive, telecommunications, and industrial automation. LDOs provide stable voltage output with minimal input-output differential, making them ideal for battery-powered devices and noise-sensitive applications. Key products include adjustable/fixed-output LDOs, high-current LDOs, and ultra-low-noise variants. Major manufacturers often integrate features like thermal shutdown and current limiting in their LDO offerings.
