Ultra-small LDO linear regulator helps double battery life in power-sensitive electronics

Texas Instruments introduced an ultra-low-power LDO linear voltage regulator with what is claimed to be the industry’s lowest quiescent current (IQ) of sub-25nA – one-tenth that of competing devices. The new regulator offers low IQ control at light loads even in dropout conditions, enabling engineers to double the battery life of their applications. Furthermore, it offers a best-in-class transient response for faster wake-up, enhancing application response times and dynamic performance. The small solution footprint assists engineers to design smaller, lighter and more efficient products quickly by decreasing power-supply solution size, and its common industry packages provide for pin-to-pin drop-in replacement in existing designs.

The device assists engineers to solve critical design challenges in multiple power-sensitive, high-precision and low-power applications including the grid infrastructure, building automation, medical equipment and wearables markets.

The device joins the company’s portfolio of low-IQ LDO linear regulators that allow designers to prolong system life. By implementing the device with other ultra-low IQ devices, engineers can further optimise battery life and performance in their systems.
