A linear regulator operates by using a voltage-controlled current source to force a fixed voltage to appear at the regulator output terminal. The control circuitry continuously monitors (senses) the output voltage, and adjusts the current source (as required by the load) to hold the output voltage at the desired value.. 4.2 Multi-Phase Buck Regulators. Multi-phase Overview. The idea of a multi-phase buck regulator is to put several buck regulators in parallel but have them operate in an interleaving manner. See figure below. The three-phase synchronous buck regulator has identical components for each phase, but the switching actions are 120 degrees out of phase.. 2.4 NMOS. Linear-Regulator Operation.

The IC has features such as safe operating area protection, thermal shut down, internal current limiting which makes the IC very rugged. Output currents up to 1A can be drawn from the IC provided that there is a proper heat sink. .
