Analog Voltage Regulators are DC-to-DC Converters that regulate their output with out regard to the load attached [to a point]

VRM: Voltage Regulator Module. Intel has standards which define DC-to-DC converter modules for their microprocessors.
The current standard / Design guideline is VRM 9.1. The standard defines a board size, pinout, output voltage/current, operation and more.
LDO: Low DropOut regulators reduce the difference between Input voltage [Vi], and Output voltage [Vo].
An LDO regulator will allow for less then a 1 volt difference between Input and Output voltages and still function.
