TINA/Spice/OPA548: OPA548 AC Current Regulator

Mustafa,

I'm not sure what you mean by saying "alternating current/voltage regulator" but if you mean whether OPA548 can sink and source current then that is correct - since OPA548 has class AB output stage, it can sink/source up to 3A (see below).  Of course, the higher output current requires further output voltage swing from the rail, which is shown in the table below.

You may simulate +/-5V output with 1A peak current, which requires 5ohm load resistor  - see below output.

I have attached below Tina-TI schematic you may use for your own simulations.
