Assuming a lower output current of 10mA, the maximum
input voltage can be recalculated:
Maximum input voltage for a 10mA load current at 50°C
ambient temperature is 34.9V, utilizing virtually the entire
operating voltage range of the device.
Adjustable Regulator Application
The MIC5233BM5 can be adjusted from 1.24V to 20V by
using two external resistors (Figure 1). The resistors set
the output voltage based on the following equation:
