9 Power Supply Recommendations

The device is designed to operate from an input voltage supply range between VOUT + 1 V up to a maximum of 26 V. This input supply must be well regulated and free of spurious noise. To ensure that the LM2941 output voltage is well regulated, the input supply should be at least VOUT + 2 V.
