Notes:

1. Load regulation is specified for an output load change of 10% to 100%.

2. Measured at an internal IC junction.

3. Quiescent current is specified at 0% load for Vin = min to max.

4. This regulator is not designed to be used in parallel with another unit to increase output power.

5. The input should not exceed the range given in the model selection chart. Exceeding this limit could

damage the unit.

For right-angle pin option, add suffix “L” to model number (i.e. SR7820-05WL)
