Linear Technology's LT3080IDD-1#TRPBF Adjustable 1.1A Single Resistor Low Dropout Linear Regulator

The LT3080IDD-1#TRPBF is a versatile and robust adjustable linear regulator from Linear Technology, designed with precision and flexibility in mind. It is capable of delivering up to 1.1A of continuous output current with a dropout voltage of typically 300mV at full load. This makes it an excellent choice for applications that require a stable and reliable power supply with low voltage drop across the regulator.

One of the key features of the LT3080 is its unique single-resistor output voltage setting. Users can set the output voltage from 0V to 19.5V with only a single external resistor, simplifying design and reducing component count. This feature is particularly beneficial in applications where space is at a premium and design simplicity is desired.

The device operates with a wide input voltage range from 1.2V to 20V, which makes it suitable for a variety of power sources, including single-cell Li-Ion batteries, multi-cell batteries, automotive inputs, and industrial supplies. The LT3080IDD-1#TRPBF is also stable with ceramic output capacitors, ensuring reliable performance even with modern low-ESR capacitors.

Thermal performance is another area where the LT3080 excels. It comes in a thermally enhanced 12-lead DFN package, which helps to dissipate heat more effectively. This, along with its internal protection circuitry that includes current limiting and thermal shutdown, ensures that the device operates within safe temperature ranges under all conditions.

Additional features of the LT3080IDD-1#TRPBF include a low shutdown current of

Overall, the LT3080IDD-1#TRPBF is a highly reliable and easy-to-use adjustable LDO regulator that can be used in a wide range of applications, from sensitive RF applications to rugged industrial power systems. Its combination of low dropout performance, thermal efficiency, and design flexibility make it a strong contender for any power regulation needs.
