In summary, a voltage regulator should be chosen based on the Vin expected, Vout needed, and load current requirements. The combination of these factors will determine whether a switching or linear regulator will be most appropriate. Linear regulators provide basic voltage regulation with a high degree of supply quality and integrity. LDO regulators are a type of linear regulator in which the voltage required to operate the device is very minimal, that is, the input voltage is very close to the output. Analog Devices’ offers a wide variety of performance LDOs suitable for powering mixed-signal, RF, Audio, GPS systems, and low voltage digital cores.
