The AZ1086S-3.3TRE1 voltage regulator belongs to the PMIC - Voltage Regulators - Linear category. It provides a steady voltage output over a specified range of temperature, line and load changes. It is especially suitable for battery-powered applications with its low operating current and high power supply rejection ratio. It is designed to offer low thermal noise, low output voltage ripple and low power dissipation. It offers an output voltage accuracy of less than or equal to ± 1%, making it suitable for managing both high and low voltage levels in a wide range of devices.

The AZ1086S-3.3TRE1 acts as a two-stage linear regulator. The first stage contains two current mirrors capable of providing a maximum of 20mA of current, while the second stage acts as an error amplifier. The error amplifier senses any fluctuations in the output voltage due to line or load changes and adjusts the voltage accordingly. This ensures a steady output voltage within the specified tolerances. It also has an over-temperature protection feature which shuts down the output voltage automatically when the temperature exceeds a set threshold.

The input voltage range for the AZ1086S-3.3TRE1 is from 2.7V to 5.5V. It is specified for an output voltage of 3.3V with a voltage tolerance of ≤±1%. It has a maximum output current of 800mA, switching frequency of 230kHz and a line regulation of ≤±0.3%. Its quiescent current consumption is low, around 4mA at the maximum load and temperature. It has a high output voltage ripple and thermal noise of 10mV and 60uV, respectively. It also has a high power supply rejection ratio (PSRR) of 82dB, bettering most other regulators in its class.

The AZ1086S-3.3TRE1 is designed with a good balance of specifications and performance to meet the demands of battery powered devices. With its high power supply rejection ratio, low operating current and output voltage ripple, it is ideal for use in many diverse applications. These include battery-powered electronic systems such as portable devices, modems and routers, and computer systems. It is also suitable for automotive applications, as it can handle transients, which are common in car power systems.

In conclusion, the AZ1086S-3.3TRE1 voltage regulator is a well-rounded and cost-effective linear regulator. Its low operating current, high PSRR, and high output voltage accuracy make it a great choice for battery-powered applications and automotive applications. Its excellent specifications, performance, and cost make it a great option for many different applications, from portable devices to computer systems.
