1. Thermal resistance test board
Size: 76.2mm * 114.3mm * 1.6mm(1S0P)
JEDEC standard: JESD51-3, JESD51-7
2. Assume no ambient airflow.
3. Load and Line regulation are specified at constant junction temperature. Change in V O due to heating effects must be taken
into account separately. Pulse testing with low duty cycle is used.
4. C ADJ , when used, is connected between the adjustment pin and ground.
