9 Power Supply Recommendations

This device is designed to operate from an input supply voltage range of 1.8 V to 5.5 V. The input supply should

be well regulated and free of spurious noise. To ensure that the LP5951 output voltage is well regulated, the

input supply should be at least VOUT + 0.5 V, or 1.8 V, whichever is higher. A minimum capacitor value of 1-μF is

required to be within 1 cm of the IN pin.
