![A useful on-card regulator must include everything within one package, including the series-pass transistor. The author has previously advanced arguments against including the pass trasistor in an integrated-circuit regulator [1]. First, there are no standard multilead power packages. Second, integrated circuits necessarily have a lower maximum operating temperature because they contain low-level circuitry. This means that an IC regulator needs a more massive heat sink. Third, the gross variations in chip temperature due to dissipation in the pass transistor worsen load and line regulation. However, these problem can be largely overcome using the new techniques, especially for the kind of regulator required by digital systems.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:ynia5stn2qgmkwbwfrq7j4ai/bafkreiara46hsbygyjgjq63an4utnn6b4zfqevzzvaq22np3hb7xjuptvq)
