LT3092ITS8 - Programmable Current Source

The LT3092ITS8 is a highly versatile, programmable current source from Linear Technology, designed to deliver a precision current output ranging from 0.5µA to 200mA. This innovative component is housed in a compact TSOT-23 package, making it an ideal choice for space-constrained applications. It is part of Linear Technology's esteemed line of robust current sources that cater to a broad spectrum of uses, from biasing and sensing to power regulation in various electronic systems.

At the heart of the LT3092ITS8 is a unique, patented design that allows for easy programmability with only two resistors. This feature simplifies the process of setting the output current, providing flexibility and precision without the need for complex external circuitry. The device's wide voltage range of 1.2V to 40V and its ability to operate in a reverse voltage configuration enhance its adaptability across different applications.

One of the standout features of the LT3092ITS8 is its excellent temperature stability, which ensures consistent performance across a temperature range of -40°C to 125°C. The low temperature coefficient, typically 20ppm/°C, along with its low output drift, contribute to the device's reliability and precision in demanding environments.

The LT3092ITS8 also boasts impressive safety features. It includes thermal shutdown and current limiting, which protect the device and the application from potential damage due to overheating or excessive current conditions. Furthermore, the current source has a high PSRR (power supply rejection ratio) of 80dB at 1kHz, which means it delivers a stable output current despite variations in the input voltage, making it exceptionally immune to power supply noise.

Whether you're designing battery chargers, LED drivers, or adjustable constant current sources, the LT3092ITS8 from Linear Technology offers a high degree of functionality in a small form factor. Its ease of use, combined with its robustness and precision, makes it a valuable component for engineers and designers seeking a reliable current source solution.
