These devices, which operate over an input range of 2.5V to 10V, are stable with any capacitor ≥ 0.47μF. The 2.5V to 10V input voltage range, combined with 3.2μA quiescent current, makes this device particularly well-suited for two-cell alkaline, and two-cell lithium, and other low quiescent current sensitive battery applications. The low dropout voltage and low quiescent current allow operation at extremely low power levels. Therefore, the devices are ideal for power battery management ICs. Specifically, because the device is enabled as soon as the applied voltage reaches the minimum input voltage, the output i...
