GENERAL DESCRIPTION
The AMS2905 series of adjustable and fixed voltage regulators are designed to provide 500mA output current and to operate down to 1V input-to-output differential. 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 inthe low profile surface mount TO-252(DPAK), SOT-223 and SOT-89 packages.
