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

VIN = Max[VOUT + 1.0V or 2.3V], CIN = 1μF, COUT = 1μF, VEN = VVIN, -40 °C < Tj < 125°C. Typical values are at TA =

25°C. All specifications apply to both LDOs unless otherwise noted.
