3. In the test circuit, there is no external capacitor applied to pin 7. However, when the device is plugged into a test socket, there is usually a
very small but finite stray capacitance present, of the order of 5 pF.
4. The NCP7662 can operate without an external diode over the full temperature and voltage range. This device will function in existing designs
which incorporate an external diode with no degradation in overall circuit performance.
