Low dropout regulators (LDOs) are a simple and cost-effective way to provide a regulated output voltages from a higher input voltage. LDOs simplify the system design as an array of features that can focus on noise reduction, circuit protection, minimal power consumption, and extremely small footprints.
Featured products, which encompass a wide array of capabilities, include ultra-low IQ, high PSRR, wide input voltage, small size and high current LDOs.
Electronic miniaturization is now mainstream requiring chip-scale or near chip-scale components to meet the size and density requirements. Diodes' Small-size LDOs accomplish this challenging task and deliver the same high-quality performance while consuming as little space as possible.
