... Forcing the enable pin high enables the output voltage. Input Capacitor The MIC5233 has high input voltage capability up to 36V. The input capacitor must be rated to sustain voltages that may be used on the input. An input capacitor may be required when the device is not near the source power supply or when supplied by a battery ...
