35 / 39 page  DocID025777 Rev 1 35/39 ST2100 Electrical characteristics 39 7.4 Power-up and reset sequence The master reset (MRESET) must be released after the VDD2.5 power supply is stable for a time interval of 2 ms, which is the start-up time of the main oscillator, as illustrated in Figure 6. Figure 6. Power-up and reset sequence 7.5 Internal 2.5 V linear regulator The internal linear regulator specified in Table 24 provides a regulated 2.5 V power supply for on-chip AFE, OSCI, PLL, USB PHY, PCIe PHY and SYNTH functional blocks. The 2.5 V regulator cannot be used to supply external devices. Table 24. Internal 2.5 V voltage regulator specifications Symbol Parameter Min. Typical Max. Unit VDD3.3 REG Supply voltage for 2.5 V linear regulator 2.97 3.3 3.36 V VDD2.5 REG Output voltage of 2.5 V linear regulator 2.25 2.5 2.75 V ILOAD2.5 REG Output current of 2.5 V linear regulator - - 150 mA |
