An input bypass capacitor is recommended if the regulator is located more than 4″ from the supply
input filter. The LM2935 is not internally compensated and thus requires an external output capacitor
for stability. A minimum capacitance of 10 µF is recommended. The actual capacitance value is
dependent upon load current, temperature, and the capacitor's equivalent series resistance (ESR).
The least stable condition is encountered at maximum load current and minimum ambient
temperature.
This device contains 29 active transistors.
