ISL80083
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. (Continued)
