11 Power Supply Recommendations

This device is designed to operate from an input supply voltage range of 1.6 V to 6.5 V. The input supply must be well regulated and free of spurious noise. To ensure that the LP5912 output voltage is well regulated and dynamic performance is optimum, the input supply must be at least VOUT + 0.5 V. A minimum capacitor value of 1 µF is required to be within 1 cm of the IN pin.
