The MAX6484BL33BD3: Surface-mount only.

Output and control — fixed 3.3 V with supervision

Single positive regulator with a fixed 1.2 V or 3.3 V output — the MAX6484BL33BD3 is the 3.3 V fixed variant. The adjustable version allows setting the output anywhere from 1.2 V up to 5.5 V via external resistors, but this order code ships at 3.3 V out of the box. Enable and Reset control pins let you sequence the rail and supervise the MPU reset line without an external supervisor IC. Quiescent current is 136 µA typical — not an ultra-low-Iq part for always-on battery applications, but acceptable for a peripheral rail that stays powered during active operation. The protection set covers over-current, over-temperature, reverse polarity, and short circuit, giving the downstream load a solid fault barrier.

RoHS non-compliant per the manufacturer's declaration. If your assembly line or target market requires RoHS exemption, this part may still be acceptable under certain exemptions (e.g., lead in solder for high-reliability applications), but verify compliance with your compliance team before committing the BOM.

Frequently asked questions

What package does the MAX6484BL33BD3 come in?

It is supplied in a 6-UFBGA, CSPBGA package (6-UCSP, 1.52x1.52 mm). The Bulk packaging option means it ships in non-tape-and-reel form — confirm the reel quantity with your distributor if you need automated pick-and-place.

What protection features does this LDO include?

Over-current, over-temperature, reverse polarity, and short-circuit protection are all integrated. No external protection diodes are needed for the output.

Is the MAX6484BL33BD3 RoHS compliant?

No, Analog Devices lists it as RoHS non-compliant. Check with your compliance team for applicable exemptions before using it in RoHS-restricted markets.
