Low dropout regulators (LDOs) are a simple and cost-effective way to get a regulated output voltage from higher input voltage. LDOs provide great simplicity for the system design as they are widely used in broad applications due to no switching noise and small size.
Our featured products, which encompass a wide array of capabilities, include ultra-low IQ, high PSRR, wide input voltage, small size and high current LDOs.
Today's electronic designs are getting more and more dense, and PCB space is consequently getting smaller and smaller. Diodes' Small-size LDOs accomplish this challenging task and deliver the same high-quality performance while consuming as little space as possible.
