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

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.

Voltage Regulator Block Diagram

POL, Point-of-Load, a term used to indicate that a regulator is located next to load [circuit] using the regulator.
POS, Point-of-Source, a term used to indicate that a regulator is located next to source that requires the regulator.
Neither term describes a regulator, only its placement within a circuit or system. Any voltage regulator could meet the requirements, depending on its placement.
