... Refer to Application Note 9 for further details and examples on thermal design and heat sink specification. Output Capacitor The MIC39300/1 requires an output capacitor to maintain stability and improve transient response. Proper capacitor selection is important to ensure proper operation. The MIC39300/1 output capacitor selection is dependent upon the ESR (equivalent series resistance) of the output capacitor to maintain stability ...

... MIC39300/39301 Minimum Load Current The MIC39300/1 regulator is specified between finite loads. If the output current is too small, leakage currents dominate and the output voltage rises. A 10mA minimum load current is necessary for proper regulation. Error Flag The MIC39301 version features an error flag circuit which monitors the output voltage and signals an error condition when the voltage drops 5% below the nominal output voltage ...
