Boldface specifications apply over the TA range of -40°C to +125°C. Parameters Sym. Min. Typ. Max. Units 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. |
