The MAX1976ETT130+ is an active-production LDO regulator from Analog Devices, rated for 300 mA continuous output current. ROHS3 compliant, per the manufacturer's lifecycle record — no lead-free transition or obsolescence concern on this order code.
300 mA LDO — what the rating means for fit
The 300 mA output ceiling sets the load budget for the regulated rail — a downstream load pulling 250 mA continuous leaves 50 mA headroom for inrush or transient peaks without dropout. Falls in the Power Management (PMIC / Gate Driver) category — typically used to supply a clean, low-noise voltage rail to analog front-ends, MCU core supplies, or sensor bias circuits.
