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. θJA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
5. For θJC, the “case temp” location is taken at the package top center.
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, VIN_HOST or VIN_REMOTE = 3.3V. For LDO, VSELECT = VOLDO + 0.5V to
5.5V, L1 = 1.0µH, C1 = C4 = C5 = 10µF, C2 = C3 = C6 = 1µF, IOUT = 0A for SMPS and LDO (see Figure 1 for more details). Boldface limits apply across
the operating temperature range, -40°C to +85°C.
