Texas Instruments has introduced an ultra-low-power Low-Dropout (LDO) linear voltage regulator with the lowest quiescent current (IQ) of sub-25nA - one-tenth that of competing ultra-small devices. The new regulator features low IQ control at light loads even in dropout conditions, allowing engineers to at least double the battery life of their applications. In addition, it provides 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.
The device joins TI’s portfolio of low-IQ LDO linear regulators that enable designers to prolong system life. By implementing the TPS7A02 with other ultra-low IQdevices - such as TI’s family of ultra-low power MSP430 microcontrollers (MCUs), the SimpleLink CC2642R MCU, the TLV8802 nanopower operational amplifier or the TMP1075 low power temperature sensor - engineers can further optimise battery life and performance in their systems.
