PMIC - Voltage Regulators - Linear

The AZ2940T-3.3E1, linear regulators are integrated power controllers designed to provide a regulated output voltage from an external power source. They are capable of delivering up to 5 amps (1.8-5.2V) of output current. These linear regulators use a single stage of modulation, providing a low output impedance of 1 mΩ and a maximum current of 7.5 A.

The AZ2940T-3.3E1 has been designed for applications requiring an accurate low output voltage from an external power source. Typical applications include microprocessors, microcontrollers, digital systems, computers, and other electronic and industrial circuits.

The AZ2940T-3.3E1 comes with an internal adjustment circuit which provides an easier reference adjustment than the older “off the shelf” devices. It is also capable of operating reliably at input supplies of up to 16V.

The working principle of the AZ2940T-3.3E1 is simple: it is a resistor network consisting of several resistors, connected in series to create a voltage divider circuit. The output is regulated by a feedback loop, which senses the voltage at the output of the voltage divider and adjusts the resistors in the divider circuit to maintain a constant output voltage.

When a load is applied, the output voltage will drop, and the feedback loop will cause the resistors in the voltage divider to increase, providing a higher output voltage. Similarly, when a load is removed, the output voltage will increase and the feedback loop will cause the resistors in the voltage divider to decrease, providing a lower output voltage.

The AZ2940T-3.3E1 also comes with other features that make it easy to use and reliable. It is built with a thermal shutdown protection circuit that will shut down the device if the temperature of the output exceeds the specified maximum temperature. It also has a current limit protection feature which will limit the output current of the device in case of an overload.

These features have made the AZ2940T-3.3E1 a popular choice for applications that require a reliable and accurate low voltage output, such as microprocessors, microcontrollers, digital systems, and computers. Its ease of use and excellent performance have established it as one of the most reliable and efficient linear regulators available.
