Product details

What this part is and where it fits

The MAX653CSA+ from Maxim Integrated is a step-down (buck) switching regulator delivering up to 225 mA from a 4 V to 11.5 V input rail. Output is adjustable down to 1.3 V or fixed at 3 V. In an 8-pin SOIC surface-mount package, it targets low-power point-of-load conversion where board space is tight and a single output rail is needed.

Key ratings and what they mean for the BOM

Commercial temperature range (0°C to 70°C) limits deployment to indoor, climate-controlled equipment. Not rated for automotive under-hood or industrial enclosures where ambient exceeds 70°C.
