FUNCTION DESCRIPTION

The

The

AMS1085 has two versions: the fixed output version and the adjustable output version. Output voltages can be

1.5V, 1.8V, 2.5V, 3.3V, and 5.0V.On-chip thermal shut-down circuit provides protection against overload

and overheating that would create excessive junction temperature.

The adjustable output version requires a 22 μF or bigger tantalum capacitor at output for

AMS1085 stability. The

capacitor for fixed output version can be smaller and should be determined base on actual application. Generally,

the stability of linear regulator stability decreases with output currents increase.
