NOTE :
1. Line regulation is per 1.0% change in input voltage.
2. Load regulation is for load change from 100% to 20%.
3. The output noise is measured with 0.33uF ceramic capacitor.
4. Maximum case temperature under any operating condition should
not be exceeded 100℃.
5. The EC1TA2XN input terminal need to parallel with 4.7uF ceramic
capacitor.
