Product Overview: TPS7A02 Low-Dropout Regulator
The TPS7A02 is an ultra-low quiescent current, low-dropout (LDO) linear voltage regulator developed by Texas Instruments. Designed for applications requiring high efficiency and extended battery life, the TPS7A02 offers a combination of low power consumption, high performance, and compact size. This device is ideal for use in portable and battery-powered systems where power efficiency is critical.
With a quiescent current of only 25 nA (typical), the TPS7A02 significantly reduces power consumption in standby and active modes. It supports input voltages ranging from 1.5 V to 6.0 V and provides output voltages from 0.8 V to 5.0 V, making it highly versatile for a wide range of applications. The device is available in multiple fixed output voltage options and also supports adjustable output configurations.
