The 8-SOIC package is a standard footprint, reflow-friendly, and widely second-sourced for assembly. ## Lifecycle and sourcing reality The MAX856ESA+ is listed as Active and ROHS3 compliant. That means you can qualify it into a new design without worrying about a sudden obsolescence-driven respin. No single-supply dependency here.","metaTitle":"Maxim MAX856ESA+ Step-Up Regulator, 500mA, 8-SOIC","metaDescription":"Maxim MAX856ESA+ boost converter: 0.8V-6V input, programmable 3.3V/5V output, 500mA switch, 500kHz.
