Expert 3330 points
Part Number: LM317A

Hi team,

my customer wants to know specs which cannot be found in datasheet. If it's available, please provide? 

1. accuracy over the full temperature range (-40∽125 °C): 

2. quiescent current:

3. temperature drift:

4. output resistance:

thanks,

Yang

    Hi Yang,

    All of these parameters can be found in the datasheet.  

    1. accuracy over the full temperature range (-40∽125 °C): 

    The output voltage is equal to the internal reference voltage gained by your external resistor divider.  As such, the reference accuracy is your internal accuracy for this regulator.

    2. quiescent current:

    Please note that LM317A does not have a GND reference, as such the terms Iq and Ignd are not used.  Instead the current required to power the linear regulator will be Iadj.

    3. temperature drift:

    4. output resistance:

    Very Respectfully,

    Ryan
