9 Power Supply Recommendations

This device is designed to operate from an input supply voltage range of 2.2 V to 5.5 V. The input supply must be well regulated and free of spurious noise. To ensure that the LP5907-Q1 output voltage is well regulated and dynamic performance is optimum, the input supply must be at least VOUT + 1 V. A minimum capacitor value of 1 µF is required to be within 1 cm of the IN pin.
