AMS1117-5.0 in AMS1117 LDO Family
The AMS1117-5.0 is a fixed 5.0V low dropout (LDO) linear regulator widely manufactured by companies like Advanced Monolithic Systems and Diodes Incorporated. Designed to provide up to 1A of output current, it is a staple in power management for digital circuits, bridging the gap between higher-voltage DC supplies and standard 5V logic. Its popularity stems from its low cost, minimal external component requirements, and robust performance in SOT-223 and TO-252 packaging.
Variants in This Sub-Family
Variants within the AMS1117-5.0 sub-family primarily differ by manufacturer-specific tolerances, thermal resistance ratings of the package, and operating temperature ranges. While most utilize the SOT-223 footprint for thermal dissipation, some variants are offered in SO-8 or TO-252 packages to handle higher power dissipation requirements. Grade 'A' variants often denote tighter output voltage accuracy, while industrial versions extend the operating temperature from -40C up to 125C.
