AZ1084S2-3.3TRE1 Application Field and Working Principle

AZ1084S2-3.3TRE1 is a regulator in the wide range of linear voltage regulators produced by Diodes Incorporated. This cast part has replaced the 78033 series, making AZ1084S2-3.3TRE1 a great choice for use in modern electronics. It operates from an input voltage range of 6.5V to 24V, to produce output voltages of 3.3V.

AZ1084S2-3.3TRE1 belongs to PMIC - Voltage Regulators - Linear family and can be used in numerous applications, such as automotive (24V), industrial, communications and consumer electronics, among others. This Fully Integrated Regulator provides low quiescent current, low noise, high PSRR and programming flexibilities, a very small footprint and a reprogrammable current limit. It also features over-voltage, under-voltage protection, thermal shutdown, current limiting protection and soft-start.

AZ1084S2-3.3TRE1 is able to provide a precise and stable output voltage with good transient performance and temperature stability. It consists of a voltage reference, error amplifier, PWM comparator and a driver circuit.

The voltage reference is a band-gap type reference that provides a stable and low-temperature-coefficient reference voltage. The output of the reference is buffered by an error amplifier that has a high slew rate, compensated and internally trimmed to maintain accuracy over the environmental and load conditions. The logic Comparator (PWM) monitors the voltage at the load, and compared to the voltage reference, the PWM comparator adjusts the current through the series pass element (MOSFET) to maintain the output voltage within +/-1% error.

A high-transition-rate driver and a patented boundary-mode control not only provide fast response against line and load transients, but also make the chip immune to output capacitance, inductance and ESR. The AZ1084S2-3.3TRE1 also has a programmable current limit feedback, which provides self limiting during current overload conditions.

The AZ1084S2-3.3TRE1 integrated circuit provides many convenient features designed to make system design, debugging and operation much easier. Its advanced power-saving modes reduce the quiescent current, while making a simple and quick switch to the ECO mode when the output is slightly loaded. This combination of features simplifies system design and guarantees a high-performance, low-noise and reliable power solution.

To sum up, AZ1084S2-3.3TRE1 is an ideal linear voltage regulator for applications requiring precision voltage regulation, low noise, low quiescent current, high PSRR and programming flexibilities. It is very useful in multiple applications with its wide input voltage range, low quiescent current and reprogrammable current limit.
