Notes to Specifications
1. Some parameters are not directly measured but are verified as part of another test
2. Measurement guaranteed for a bandwidth of 20 MHz. Tested with a bandwidth of 20KHz to 2MHz.
3. Regulation measured for all combinations of line and load conditions shown. Worst limit is presented for
each parameter.
