CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product reliability and

result in failures not covered by warranty.

NOTE:

5.

θJA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. See

Tech Brief TB379.

Electrical Specifications

TA = -40°C to +85°C; VIN = (VO + 0.5V) to 5.5V with a minimum VIN of 1.5V; CIN = 1µF; CO = 1µF; Parameters

with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits

established by characterization and are not production tested.
