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.
NOTES:
1. VDS (Drain to Source) specification for internal high-side and low-side MOSFET.
2. 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 = +25°C. VIN = 12V, VOUT = 1.5V. CIN = 220µFx1, 10µF/Ceramicx2, COUT = 330µF (ESR = 10mΩ),
22µF/Ceramicx3. 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.
