GENERAL DESCRIPTION
The
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 offered in the low profile surface
mount TO-252(DPAK), SOT-223 and SOT-89 packages.
