The dropout voltage of the device is guaranteed maximum 1.
3V at maximum output current, decreasing at lower load currents.
On-chip trimming adjusts the reference voltage to 1%.
Current limit is also trimmed, minimizing the stress under overload conditions on both the regulator and power source circuitry.
The AMS2905 devices are pin compatible with other three-terminal regulators and are offered in the low profile surface mount TO-252(DPAK), SOT-223 and SOT-89 packages.
