† 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.

VVIN = 4.5V to 42V

IDD_OUT = 1mA

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.
