Product details

300 mA LDO — active, RoHS non-compliant

The MAX1976EZT180: One gotcha: this part is RoHS non-compliant. That means it uses lead-bearing solder finish — fine for legacy assemblies or military/aerospace builds with a RoHS exemption, but it won't pass a standard lead-free reflow profile. If your line runs SAC305, this isn't the drop-in.

Supplied in bulk, not tape-and-reel — expect loose tubes or trays. The package itself is a small-outline SOT-23 or similar 5-lead form factor typical of Maxim's LDO family, which reflows cleanly under hot air with a modest thermal pad underneath. For a 300 mA LDO, the dropout voltage at full load is typically under 200 mV — the exact figure depends on the output voltage variant. The input rail needs to stay above Vout + Vdo across the load range, or the output drops out of regulation.

Frequently asked questions

What is the closest pin-compatible alternative to MAX1976EZT180?

No official pin-compatible successor or cross-reference is recorded for this order code. The MAX1976 family shares the same pinout across output voltage options, but a different voltage variant (e.g., MAX1976EZT150 for 1.5 V out) is not a functional substitute unless the downstream rail matches exactly. For a parametric replacement, look at other 300 mA LDOs in the same SOT-23-5 footprint from Maxim or Texas Instruments — but confirm the output voltage, dropout, and enable logic before committing the BOM.

What compliance documentation does Maxim provide for MAX1976EZT180?

The part is RoHS non-compliant (lead-bearing finish). For military or high-reliability builds, request the full material declaration and the latest PCN from the distributor at RFQ time.
