The MAX881REUB+: RoHS3 compliance means it meets the latest EU environmental restrictions — no exemption expiry to track.
Negative rail from a positive supply
It is specifically listed for charge pump and wireless device applications — think generating a -5 V bias for an RF switch or a negative rail for an op-amp in a battery-powered sensor.
Package and hand-solderability
Housed in a 10-pin TFSOP/MSOP package (0.118-inch width, 3.00 mm) with a supplier device package of 10-uMAX/uSOP. The 0.50 mm pitch is hand-solderable with a fine tip and magnification — a hobbyist can breadboard it with a SOIC-to-DIP adapter, though a hot-air station makes rework cleaner. Supplied in a Tube — typical for small MSOP parts; order multiples if you need reel quantities for production.
