概述
Description
Key features of the LT1763CDE include an input voltage range of 1.8V to 20V, an output current capability of up to 500mA, and a very low dropout voltage. It also offers excellent line and load regulation, with a typical output voltage accuracy of 1.5%. The regulator includes internal protection features such as current limiting and thermal shutdown to enhance reliability.
The "CDE" in the part number refers to the package type, which is a 5-lead plastic DFN (Dual Flat No-leads) package, providing good thermal performance and a compact footprint suitable for space-constrained applications. This LDO is commonly used in battery-powered devices, communication equipment, and other applications requiring efficient regulation and low noise performance.
