Note 1: R LAD (R F + R G in Figure 4-1) connects V REF , V OUT and the inverting input of the internal amplifier. The MCP6S22 has
V REF tied internally to V SS , so V SS is coupled to the internal amplifier and the PSRR spec describes PSRR+ only. We
recommend the MCP6S22’s V SS pin be tied directly to ground to avoid noise problems.
2: I Q includes current in R LAD (typically 60 μA at V OUT = 0.3V). Both I Q and I Q_SHDN exclude digital switching currents.
3: The output goes Hi-Z and the registers reset to their defaults; see Section 5.4, “Power-On Reset”.
