Working Principle of RT9164A-33GLR

The RT9164A-33GLR is a low-dropout linear voltage regulator. It is designed to provide a regulated 3.3V output voltage from a wide range of input voltage sources with excellent load and line regulation. The device operates with a wide input supply range from 0.8V to 12V and can be configured to operate with an output voltage of anywhere from 1.2V to 5.0V. It is also able to supply up to 1.5A of output current.

The device works by controlling the voltage across an internal N-channel MOSFET load switch. When the device is enabled, the voltage across the MOSFET is regulated to a constant output voltage. This is done by the device’s internal gain control circuit which compares the feedback voltage with a precision reference voltage and adjusts the MOSFET\'s gate voltage accordingly. The device is able to keep the output voltage within +/- 2.0 % of the set point, even over a wide range of input voltage and output current conditions.

The device also has a variety of protection features which include output short-circuit and over-current protection, as well as over-temperature protection. It also incorporates a soft-start circuit to help reduce in-rush current at turn-on.
