The MAX1976EZT285 is a 300 mA low-dropout linear regulator from Maxim Integrated. It is designed for point-of-load regulation where a clean, stable supply rail is needed from a slightly higher input voltage. The 300 mA output current rating sets the load budget: this part handles local regulation for a small MCU, a sensor front-end, or a low-power RF stage, but not a multi-amp rail.
RoHS non-compliant — a sourcing constraint
This part is RoHS non-compliant. It is suited for legacy production runs, military/aerospace contracts with leaded-solder exemptions, or repair depots where the original BOM specified tin-lead finish.
