Walter, I would take this an additional step and always use the STK392 -180 for the -110 in any brand set. I placed a note in my parts log to substitute the -180 for the -110. Don't trust my memory. I do the same thing for the STK730 series regulators. For the -010, -020, -030, -040, or -130--I use an STK730-090. Is rated higher than the rest. Besides, cuts down on stock and saves money by ordering in larger quantity. Probably many others, but one more I remember. I use the LA7838 for either the 7837 or the 7838. Thanks for the tip, Walter.
