Absolute Maximum Ratings
Electrical Characteristics
(VI-VO=5V, IO= 0.1A, 0
°C ≤ TJ ≤ + 125°C, PDMAX = 7.5W, unless otherwise specified)
Note :
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 VO due to heating effects must be taken
into account separately. Pulse testing with low duty cycle is used.
4. CADJ, when used, is connected between the adjustment pin and ground.
