Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may
affect device reliability.

Note that a “+”, “#”, or “-” in the package code indicates RoHS status only. Package drawings may show a different
suffix character, but the drawing pertains to the package regardless of RoHS status.
Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a
four-layer board. For detailed information on package thermal considerations, refer to

Note 1:
Limits are 100% tested at T
A
= +25°C. Limits over the operating temperature range and relevant supply voltage range are
guaranteed by design and characterization.
Note 2:
Temperature coefficient is calculated using the “box method” which measures temperature drift as the maximum voltage
variation over a specified temperature range.
Note 3:
Dropout voltage is defined as the minimum differential voltage (V
IN
- V
OUT
) at which V
OUT
decreases by 0.2% from its original
value.
V
IN
= 3.3V for output voltages of 1.25V, 2.048V, and 2.5V;
V
IN
= 5V for output voltages of 3V, 3.3V, 4.096V;
V
IN
=
5.5V for output voltage of 5V.
Note 4:
Thermal hysteresis is defined as the change in +25°C output voltage before and after cycling the device from T
