9 Power Supply Recommendations
The LP38501-ADJ and LP38503-ADJ devices are designed to operate from an input voltage supply range
between 2.7 V and 5.5 V. The input voltage range provides adequate headroom in order for the device to have a
regulated output. This input supply must be well regulated. An input capacitor of at least 10 μF is required.
