LP2998 Vref Source Sink 500uA

Other Parts Discussed in Thread: LP2998

Can the Vref output of the LP2998 source/sink 500uA?

If so, what is the regulation under that condition?

Thanks.

    The LP2998 does not have direct specification for source/sink current of the Vref output pin.

    Rather, the 'Vref Output Impedance' is specified only with a condition of Iref = -30μA to +30μA to be typically 2.5 k Ohms (+/-30uA x 2.5k Ohms = +/-75mV)
