ELECTRICAL CHARACTERISTICS
† Notice: Stresses above those listed under “Maximum
Ratings” may cause permanent damage to the device.
This is a stress rating only and functional operation of
the device at those or any other conditions above those
indicated in the operational listings of this specification
is not implied. Exposure to maximum rating conditions
for extended periods may affect device reliability.
Note 1: I_OUT is also internally limited, according
to the limits defined in the “Electrical
Characteristics” table.
2: Reference Printed Circuit Board (PCB),
according to JEDEC standard EIA/JESD
51-9.
Electrical Specifications: Unless otherwise specified, all limits are established for V_DD = 2.0V to 5.5V, T_A = +25°C
