41 / 65 page ![]() DocID18315 Rev 6 41/65 STM8T143 Electrical characteristics 64 9.4 Regulator and reference voltage Table 15. Regulator and reference voltage Symbol Parameter Condition Min. Typ. Max. Unit Cref Voltage regulator decoupling capacitance(1) -1 - 10 µF Vreg Regulated voltage during acquisition(2) 3.05 ≤ VDD ≤ 5.5 2.35 2.5 2.75 V 2.3 ≤ VDD ≤ 2.65 - VDD-0.15 - 1. Equivalent serial Rresistor ≤ 0.2 Ω at 1 MHz. 2. Operating above 3.05 V improves the device noise rejection. Between 2.65 V and 3.05 V the regulated voltage evolves gradually between VDD - 0.15 V and the regulated voltage. |
