Moreover, the book has an appendix that contains a case study. The mounting type that is recommended is Surface Mount. I have embedded a SC-74A, SOT-753 case with it in order to protect it. If you search for the AN6123MS family, you will find similar parts. In this case, MINI-5D packages the device.
