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) Tested according to JEDEC standard JESD22-A114-B.
(2) 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.
Electrical Characteristics
Unless otherwise noted V IN = 3.6V, C IN = 2.2μF, C OUTA = C OUTB = 1μF, V EN = V ENB = V IN , T A = -40 to +85°C. Typical values are at T A = 25°C. All
specifications apply to both LDOs unless otherwise noted.
