Hi Kevin,

UA78 requires a minimum biasing current of 4.5mA, which means the minimum load at the output needs to be higher than 4.5mA. This is not a lower power device, and due to the age, we don't have data for the quiescent current as quiescent current is only defined at no/very light load condition which does not apply to this part.

If this is for a new design, are you open to another newer LDO?

Please see more discussion here.
