131 / 245 page  DS12500 Rev 1 131/245 STM32MP151A Electrical characteristics 228 6.3.5 Embedded regulators characteristics The parameters given in Table 18, Table 19 are derived from tests performed under ambient temperature and VDD supply voltage conditions summarized in Table 13: General operating conditions. REG1V1 embedded regulator (USB_PHY) REG_1V8 embedded regulator (USB) Table 18. REG1V1 embedded regulator (USB_PHY) characteristics Symbol Parameter Condition Min Typ Max Unit VDDA1V1_ REG Regulated output voltage - 1.045 1.1 1.155 V CL Load Capacitor - 1.1 2.2(1) 3.3 µF esr Equivalent Serial Resistor of Cload - 0.1 25 600 mΩ Iload Static load current(2) -0 - 30 mA tSTART Start-up time. from PWR_CR3.REG11EN = 1 to PWR_CR3.REG11RDY = 1 CL=2.2uF - 93 - µs CL=3.3uF - 180 IINRUSH VDD Inrush Current to load external capacitor at start - - 50 60 mA IVDD(3) Regulator Current consumption on VDD Regulator Enabled and Iload = 0 mA - 150 205 µA Regulator Enabled and Iload = 30 mA - 176 242 1. For better dynamic performances a 2.2 μF typical value external capacitor is recommended. 2. Load is for internal STM32MP151A analog blocks, no additional external load is accepted unless mentioned. 3. Guaranteed by design. Table 19.
