Output Noise Voltage (Vn) Conditions column in Electrical Characteristics for the uPC7800A Series has "10 Hz ≤ f ≤ 100 kHz", but what does this indicate?
[Output Noise Voltage] uPC7805A
|Output noise voltage||Vn||TJ=25°C,10 Hz ≤ f ≤ 100 kHz||40||200||µVrms|
The output noise voltage is measured under the condition of setting a bandpass filter to the output pin and the measured result is expressed as the effective (root mean square) voltage value. "10 Hz ≤ f ≤ 100 kHz" indicates the bandwidth of this bandpass filter. The unit is usually µVrms.
Please explain the meanings of the units used to measure electricity.
