Hi,

Could anybody tell me the definition for its line regulation? The data sheet gives 1 mV / V, but it is not giving the definition.

Is that: 1. (Vout_H - Vout_L) / (Vin_H - Vin_L) or

2. (Vout_H - Vout_L) / Vout_norm or

3. Vout_max / Vout_norm (where Vout_max is the measured output voltage (Vout_L or Vout_H) that causes the greatest deviation from Vout_norm.) ?

Thank you!

Hello Brian Y

Sorry for the delay in answering your question.

Line regulation is calculated by your option 1. We vary the input voltage between 4.5V and 5.5V and measure the change in Viso and take the ratio. We measure this this between 10mA load and at 90mA load and set the limit based on that measurement range.

This is a type test guaranteed by design, it is not tested on each device.

Best Regards,
