Internal Bias Supply Voltage. Must be de-coupled to ground with a 0.1µF capacitor.
Pin Function
Regulator Output - LDO1.
Supply Input (LDO1/2).
Regulator Output – LDO2.
Input to POR. Connect directly to output voltage or input voltage that is to be monitored for a 0.9V
reference, or connect a resistor divider network to this pin to program the POR monitoring voltage.
Power-on Reset Output. Open drain.
POR Delay. Connect capacitor to ground to set POR delay time.
Manual Reset Input. Manually resets output of POR and delay generator. Do not leave floating.
Not internally connected.
Not internally connected.
Supply Input (LDO3).
Regulator Output – LDO3.
Ground.
LDO3 Enable Input. EN (MIC5373): Active High Input. Logic High = On; Logic Low = Off;
/EN (MIC5383): Active Low Input. Logic High = Off; Logic Low = On; Do not leave floating.
LDO2 Enable Input. EN (MIC5373): Active High Input. Logic High = On; Logic Low = Off;
/EN (MIC5383): Active Low Input. Logic High = Off; Logic Low = On; Do not leave floating.
