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:
3. θ JA 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.
4. For θ JC , the “case temp” location is the center of the exposed metal pad on the package underside.
Electrical Specifications
No load on LDO, OUT1, OUT2, V REF3 , and REF, V IN = 12V, EN2 = EN1 = VCC, VBYP = 5V, PVCC = 5V,
VEN_LDO = 5V, T A = -40°C to +100°C, unless otherwise noted. Typical values are at T A = +25°C. Boldface
limits apply over the operating temperature range, -40°C to +85°C.
