ADP3309ARTZ-3.6-R7 - High-Accuracy Micropower Regulator

The ADP3309ARTZ-3.6-R7 is a high-performance, low-dropout linear regulator from Analog Devices Inc. that delivers a fixed output of 3.6 volts. This component is part of a series designed to provide precise voltage regulation with low dropout and low quiescent current, making it an ideal choice for battery-powered applications where extended battery life is critical.

With an accuracy of ±0.8% at room temperature and ±1.4% over the entire temperature range, the ADP3309 stands out for its precision in maintaining a stable output voltage under varying conditions. The device is capable of providing up to 200 mA of output current, which is suitable for a wide range of electronic devices, including portable and wearable technology.

The ADP3309ARTZ-3.6-R7 features several protective functionalities that ensure the safety and reliability of both the regulator and the system it serves. These include overcurrent protection, which guards against excessive loads that could potentially damage the circuit, and thermal overload protection, which prevents overheating and potential thermal damage.

Furthermore, the regulator offers a low dropout voltage, typically 120 mV at 200 mA load, which allows the regulator to continue providing a stable output even when the supply voltage is very close to the output voltage. This characteristic is particularly beneficial in battery-operated devices, where the supply voltage may decline over time.

The ADP3309ARTZ-3.6-R7 is available in a compact SOT-23-6 package, making it an excellent choice for space-constrained applications. Its small footprint and low power consumption make it suitable for portable devices, where efficiency and size are paramount.

Applications for this voltage regulator are diverse and include cellular phones, digital cameras, and MP3 players, as well as other portable and handheld devices. The ADP3309ARTZ-3.6-R7 is designed to meet the needs of engineers looking for a reliable power management solution that combines high accuracy, low power consumption, and robust protection features.
