The ADP3309ARTZ-3.3-R7 is an integrated linear voltage regulator designed for use in a variety of powered electronic devices. It is capable of providing a regulated output voltage of 3.3 volts, with an output current of up to 1A. The device is designed to offer high power efficiency, excellent power supply rejection ratio (PSRR), and fast transient response to changing load conditions.

The ADP3309ARTZ-3.3-R7 is manufactured using an advanced CMOS process, making it well-suited for use in applications such as microprocessor power supplies, portable digital devices, and other embedded systems. The device provides excellent line regulation and low output noise, making it ideal for situations where power conservation and clean power are key requirements.

The ADP3309ARTZ-3.3-R7 is a two-terminal device that incorporates an input voltage (VIN), an output voltage (VOUT), and an enable pin. It features an adjustable output voltage by using two external resistors (R1, R2). The device can be enabled or disabled by controlling the enable pin (which can be connected to a logic line or open-drain). When disabled, the device draws no power from the input supply and the output voltage is in a high-impedance state.

The ADP3309ARTZ-3.3-R7 is designed to provide a precise output voltage, which is determined by the resistor values. The device monitors the output voltage and the voltage drop across a current sense resistor (RSENSE) to sense the load current and adjust the output voltage accordingly. This ensures that the device can provide a strongly regulated voltage under varying load conditions.

The ADP3309ARTZ-3.3-R7 also has an integrated thermal and over-current protection, as well as an overvoltage protection. In the event of an over-temperature condition, the device shuts off the output voltage to prevent any damage to the components or board. Similarly, if the current exceeds a certain value, the device shuts off the output voltage, protecting against overload or short circuits.

The ADP3309ARTZ-3.3-R7 is a highly versatile device that is suitable for a number of industrial, consumer and computing applications. The ability to precisely regulate the output voltage and provide robust noise immunity makes the device well-suited for powering an array of electronic devices. It can operate over an ambient temperature range of -40 to +85 degrees Celsius, providing reliable operation over extended periods under a variety of environmental conditions.
