1 Measured at full load with external input/output capacitors, refer to filter circuit 1.
2 For lower ripple refer to filter circuit 2.
3 Calculated using MIL-HDBK-217F with nominal input voltage at full load.
4 Refer to power derating graph.
All specifications typical at TA=25°C, nominal input voltage and rated output current unless otherwise specified.
