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:
4. 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.
5. JC, “case temperature” location is at the center of the exposed metal pad on the package underside.
Electrical Specifications Unless otherwise noted, all parameter limits are guaranteed over the recommended operating conditions
and the typical specifications are measured at the following conditions: TA = +25°C, VINDCD1 = 3.6V, VINDCD2 = 3.3V. For LDO1 and LDO2,
VINLDOx = VOLDOx + 0.5V to 5.5V with VINLDOx always no higher than VINDCD1, L1 = L2 = 1.5µH, C1 = 10µF, C4 = C5 = 4.7µF,
C2 = C3 = C6 = C7 = 1µF, IOUT = 0A for DCD1, DCD2, LDO1 and LDO2 (see Figure 1 on page 1 for more details). Boldface limits apply over the operating
temperature range, -40°C to +85°C.
