Conditions

Note 1:

Refer to Section 14.0 “Power-Down Mode (Sleep)”.

2: VDD is the voltage present at the VDD pin.

3: Dropout voltage is defined as the input-to-output voltage differential at which the output voltage drops 2%

below its nominal value measured at a 1V differential between VIN and VDD.

4: Ensured by design, not production tested.

5: These parameters are characterized, but not production tested.

6: The VDD LDO will limit the total source current to a maximum of 35 mA. Individually each pin can source a

maximum of 15 mA.
