LT3060ETS8/LT3060ITS8 Low Dropout Linear Regulator

The LT3060ETS8/LT3060ITS8 from Linear Technology is a high-performance, low dropout linear regulator designed for precision, low power applications. This regulator provides an adjustable output from 1.2V to 45V with a single resistor, and it is capable of delivering up to 100mA of continuous output current. The LT3060 series stands out for its low noise performance and high power supply rejection ratio (PSRR), making it an ideal choice for sensitive RF and analog circuitry that requires a clean power supply.

One of the key features of the LT3060ETS8/LT3060ITS8 is its low quiescent current, which is only 30μA in operation and drops to less than 3μA in shutdown. This characteristic is essential for battery-powered and energy-efficient systems, as it helps to extend the battery life and reduce power consumption when the device is not in active use.

The device comes in a compact SOT-23 package, which makes it suitable for space-constrained applications. The LT3060ETS8 variant is optimized for operation from -40°C to 125°C, while the LT3060ITS8 version operates in the extended temperature range from -40°C to 150°C, ensuring reliable performance in a wide range of environmental conditions.

Additional features include internal protection mechanisms such as overcurrent protection, reverse battery protection, and thermal limiting, which safeguard the device and the load from adverse conditions. The LT3060ETS8/LT3060ITS8 also offers a low dropout voltage, typically 300mV at full load, which allows for efficient operation even when the input-to-output voltage differential is small.

Overall, the LT3060ETS8/LT3060ITS8 linear regulators are an excellent choice for designers looking for a reliable, efficient, and versatile power management solution. Its combination of low noise, high PSRR, and low quiescent current makes it well-suited for precision applications such as portable medical devices, portable instruments, and industrial controls, where power efficiency and signal integrity are critical.
