Exceeding the above specifications may result in permanent damage to the device or device malfunction. Operation outside of the parameters

specified in the Electrical Characteristics section is not recommended.

NOTES:

(1) Subscripting for all LDOs (LDOn), n = 1, 2, 3, 4.

(2) Tested according to JEDEC standard JESD22-A114-B.

(3) Calculated from package in still air, mounted to 3 x 4.5 (in), 4 layer FR4 PCB with thermal vias under the exposed pad per JESD51 standards.
