Integrated circuit (IC) linear voltage regulators use an active pass element to reduce the input voltage to the regulated output voltage. Some devices use bipolar transistors and others use metal-oxide semiconductor field effect transistors (MOSFETS). The use of voltage-controlled sources enables IC linear voltage regulators to force a fixed voltage to appear at the output terminal. Control circuitry monitors the output voltage and adjusts the current source accordingly. Generally, the control circuitry contains a pass device such as pair of NPN transistors driven by a PNP transistor. NPN transistors contain a P region between two N regions. PNP transistors contain an N region between two P regions.

Products & Services Related to IC Linear Voltage Regulators
DC-DC Converter Chips
DC-DC converter chips provide a regulated DC voltage output from a different, unregulated input voltage.
IC Switching Voltage Regulators
IC switching voltage regulators are integrated circuits (ICs) that store energy in an inductor, transformer, or capacitor and then use this storage device to transfer energy from the input to the output in discrete packets over a low-resistance switch.
IC Voltage Regulators, All Types
IC voltage regulators are three-terminal devices that provide a constant DC output voltage that is independent of the input voltage, output load current, and temperature. IC voltage regulators are used in power supplies that hold their output voltage constant over a wide range of load variations.
