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, 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 = 10µF, C2 = C3 = C6 = C7 = 1µF, IOUT = 0A for DCD1, DCD2, LDO1 and LDO2 (see “TYPICAL APPLICATION DIAGRAM” 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 6) TYP MAX (Note 6) UNIT |
