1. If optional VADJ and SD pin are required (as indicated in the mechanical dimensions diagram) include an E in the part number when
ordering, i.e. NGA10S1505SEC & NGA10S1505DEC.
2. Supply voltage should exceed output voltage by 1.45V.
All specifications typical at TA=25°C, nominal input voltage and rated output current unless otherwise specified.
