some cases, it's best to apply power when the mains is at its maximum value (peak of RMS = nominal voltage × 1.414), and with others it's far better to apply power as the AC waveform passes through zero volts. Iron core transformers are at their best behaviour when the mains is switched on at the peak of the waveform, while electronic loads (rectifier followed by a filter capacitor for example) prefer to be switched on when the AC waveform is at zero volts. This

reset signal is controlled by the factory-programmed reset threshold on the V supply voltage CC pin. When the voltage declines below the reset threshold, the reset signal is asserted and remains asserted for 240 ms after V CC rises above the threshold. The LM809 has an active-low RESET output, while the
regulator drops out of regulation, the output tracks the input minus a drop based on the load current. When the input voltage drops below the UVLO threshold, the regulator shuts down until the input voltage recovers above the minimum startup level. 8.3.3 Output Capacitor Selection For stable operation over
