The YL105 is a low-dropout linear voltage regulator (LDO) with a high accuracy output voltage. It's designed to provide a stable output voltage for various applications, such as consumer electronics, industrial control systems, and automotive electronics.
Unlike industrial Hall sensors (e.g., from Allegro or Melexis), the YL-105 datasheet provides . In practice, the analog output will drift significantly with temperature (±10% or more across 0-50°C). For indoor hobby projects, fine. For outdoor or industrial use? Avoid.
