Chapter 5 probably made most of an impression on the late-teenage me, because it explains voltage regulation and power ... So why is a 50-year-old regulator chip still an active product?

In some cases, the regulator element can fail, causing inadequate voltage regulation. When this happens ... s negative (-) lead to the regulator-rectifier’s positive (+) line. Apply the multimeter’s ...

A low-dropout (LDO) regulator is often used as the post regulator ... cross-regulation fail to compensate the load current impact on the output voltage regulation, although the line regulation is good ...

An HT7533 is used for voltage regulation with a Schottky diode preventing return current to the solar cell, and a DW01 circuit is used to make sure that the capacitor doesn’t overcharge.
