Part Number: LM337L
Other Parts Discussed in Thread: LM317L

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 (-25∽125 °C): 

2. temperature drift:

3. output resistance:

thanks,

Yang

    Hi Yang,

    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 LM317L 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. output resistance:

    Very Respectfully,

    Ryan
