GENERAL DESCRIPTION
The The AMS2907 series of adjustable and fixed volta ge 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 AMS2907 devices are pin compatible with other three - terminal regulators and are offere d in the low profile surface
mount TO - 252(DPAK), SOT - 223 and SOT - 89 packages.
