Pin Function
Output Voltage. When disabled the MIC5528 switches in an internal 25Ω load to discharge the
external capacitors.
Ground.
Enable Input: Active High. High = ON; Low = OFF. The MIC5528 has an internal pulldown and
this pin can be left floating.
No Connection.
Supply Input.
Exposed Heatsink Pad. Connect to GND for best thermal performance.
