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. Electrical Specifications Unless otherwise noted, typical specifications are measured at the following conditions: TA = +25°C, VINDCD1 = 3.6V, VINDCD2 = 3.3V. For LDO1 and LDO2, VINLDO = VOLDO + 0.5V to 5.5V with VINLDO always no higher than VINDCD1. L1 = L2 = 1.5µH, C1 = C4 = C5 = 10µF, C2 = 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. (Continued) PARAMETER SYMBOL TEST CONDITIONS MIN (Note 5) TYP MAX (Note 5) UNIT |
