9 Power Supply Recommendations

Follow these general guidelines when designing the power supply:

  1. The power supply should be designed to provide the recommended operating conditions (see Recommended Operating Conditions).
  2. The maximum current draw for the LMH0303 is provided in Electrical Characteristics – DC. This figure can be used to calculate the maximum current the supply must provide.
  3. The LMH0303 does not require any special power supply filtering, provided the recommended operating conditions are met. Only standard supply coupling is required.
