Note 1: “Absolute Maximum Ratings” indicate limits beyond which damage to the component may occur. Electrical specifications do not apply when operating the

device outside of its rated operating conditions.

Note 2: The ESD rating of pins 3 and 4 for the SOT-23 package, or pins 5 and 2 for the micro SMD package, is 1 kV.

Note 4: If used in a dual-supply system where the regulator load is returned to a negative supply, the LP2985LV output must be diode-clamped to ground.

Note 6: Limits are 100% production tested at 25˚C. Limits over the operating temperature range are guaranteed through correlation using Statistical Quality Control

(SQC) methods. The limits are used to calculate National’s Average Outgoing Quality Level (AOQL).

Note 7: The ON/OFF input must be properly driven to prevent possible misoperation. For details, refer to Application Hints.

at which the output voltage drops 2% below ther value measured with a 1V differential.

Note 10: Exposing the micro SMD device to direct sunlight will cause misoperation. See Application Hints for additional information.
