Analog Devices Inc. ADP3309ART-3.3-REEL7

The ADP3309ART-3.3-REEL7 is a high-precision, low-dropout voltage regulator that offers an impressive blend of features suitable for a variety of electronic applications. Manufactured by Analog Devices Inc., a leader in the semiconductor industry, this voltage regulator is designed to maintain a stable 3.3V output with an input voltage range that typically extends from 4.0V to 12V. It is available in a compact SOT-23 package, making it an ideal choice for space-constrained applications.

One of the key attributes of the ADP3309ART-3.3-REEL7 is its high accuracy. The device boasts an output voltage accuracy of ±0.8% at room temperature and ±1.4% over the entire operating temperature range, ensuring reliable performance for critical applications. This high level of precision is particularly beneficial for powering sensitive analog and digital circuits that require a stable voltage supply.

The ADP3309ART-3.3-REEL7 also features a low dropout voltage, typically just 180mV at 100mA load, which allows for efficient operation even when the input voltage is very close to the output voltage. This characteristic is especially useful in battery-operated devices, where maximizing battery life is crucial.

Additional features of this voltage regulator include a low quiescent current of 110μA (typical) that further enhances its suitability for portable equipment by reducing power consumption when in standby mode. The device also provides excellent transient response, which helps maintain voltage stability during rapid changes in load, such as when a device switches from low power to high power operation.

To ensure device protection, the ADP3309ART-3.3-REEL7 incorporates several safety features, including over-current protection and thermal overload protection. These safeguards help prevent damage to the voltage regulator and the powered device in the event of abnormal operating conditions.

The product is supplied in a tape and reel format (REEL7), which facilitates automated assembly processes, making it an efficient choice for mass production environments. With its robust feature set, the ADP3309ART-3.3-REEL7 from Analog Devices Inc. is a reliable and efficient solution for a wide range of voltage regulation requirements.
