It depends on what you mean by exactly. Voltage regulators have line and load regulation specifications. Output voltage on fixed regulators have a tolerance.I want to regulate the output of a transformer to be exactly 9v regardless of load current.
The output of the transformer is AC, a DC regulator will not regulate that. If you want regulated DC output, then you need a rectifier and smoothing capacitor before going to a D C regulator.Hello,
I want to regulate the output of a transformer to be exactly 9v regardless of load current. Will a standarad 9v DC regulator do this or is their some other way it needs to bed done?
No it needs done another way. Load current needs to be supplied by Supply current capability. The load cannot exceed the supply's capacity. If the load exceeds supply the supply voltage will begin to drop (fold over) and your transformer will begin getting hot and unfused will burn up.Hello,

'Transformer' used to mean a device with an AC input and an AC output. Nowadays the term is often also (mis)applied to a device which has a DC output. Which meaning do you intend?I want to regulate the output of a transformer
I guess this is the part where we just hang out and wait.Except that the title indicates he wants to regulate an AC voltage.
May I ask why? I'm struggling to think of a real world application where the AC voltage of a transformer secondary needs to be controlled to provide a constant AC voltage regardless of load. If you are looking for a controlled 9V DC voltage, start with 9 V AC from a transformer secondary, full wave recitify and you will still have enough headroom to use a Linear regulator like an LM317 to get 9V DC with a wide variation in load up to about 1.5AI want to regulate the output of a transformer to be exactly 9v regardless of load current.
