Product details

Buck regulator for low-power rails

The Maxim Integrated MAX653ESA+ 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 can be set to a fixed 3 V.

Package and mounting

Housed in an 8-SOIC (0.154" width, 3.90 mm body) surface-mount package. The supplier device package is 8-SOIC. Ships in Tube — store the reels dry if you're pulling from bulk inventory; the SOIC-8 is not moisture-sensitive by default, but good practice keeps the shelf life predictable.

Lifecycle and sourcing

For BOM planning, this part is a safe choice for new designs and production runs.

Frequently asked questions

Is MAX653ESA+ adjustable or fixed output?

It is listed as Adjustable (Fixed), meaning the part can be configured as an adjustable regulator down to 1.3 V, or ordered with a fixed 3 V output. The same order code covers both variants.

Does MAX653ESA+ work with 5V input?

Yes, the 4 V minimum input covers 5 V rails. A 5 V to 3.3 V conversion at 225 mA is within the part's ratings.
