LDO Linear Regulators: Introduction
The LDO linear regulators of Nisshinbo Micro Devices cover a wide operating voltage range and are suitable for various applications. We offer a wide range of high-performance products that contribute to the performance improvement of applications, such as ultra-low current consumption type, low output noise type, and high noise immunity. Furthermore, we have a wide variety of lineup such as additional monitoring function (power-good, reset function), and high precision voltage tracker for off-board sensors.
