Ultra-small LDO linear regulator

1 December 2019 Power Electronics / Power Management

Texas Instruments introduced an ultra-low-power low-dropout (LDO) linear voltage regulator with what it claims is the industry’s lowest quiescent current (IQ) of sub-25 nA. The new regulator features low IQ control at light loads even in dropout conditions, allowing engineers to significantly improve the battery life of their applications.

In addition, it provides best-in-class transient response for faster wake-up, improving application response times and dynamic performance. The small solution footprint helps engineers design smaller, lighter, more efficient products quickly by reducing power-supply solution size, and its common industry packages allow for pin-to-pin drop-in replacement in existing designs.

The TPS7A02 helps engineers solve critical design challenges in many power-sensitive, high-precision and low-power applications such as in the grid infrastructure, building automation, medical equipment and wearables markets.
