Low I_Q is a key spec for the applications where the device is operated in standby or shutdown mode for the majority of the time, so they are not drawing unnecessary power while not in use. For battery powered applications, the quiescent current is critical to extending the life of the battery and improves light load efficiency. The TPS82130 has low quiescent current of 20 uA typical. The TPSM8290x quiescent current is reduced even further to 4 uA typical. The battery in these applications are meant to last an extended amount of time without having to be replaced. The reduction of the I_Q will reduce the amount of current being drawn from the battery, therefore extending the battery life significantly.
