A transformerless power supply (TPS) is basically just a ... it is rectified through a few diodes, and maybe regulated to a maximum voltage but we’ll get to that in a minute.

Though there is nothing spectacularly challenging about a power supply from the perspective ... configured as a negative or a positive voltage series regulator, it can use an external transistor ...

This requires a relatively high-voltage input power supply and results in low power efficiency. A low dropout (LDO) linear voltage regulator is a type of linear voltage regulator circuit that works ...

A typical LDO voltage regulator normally requires an external capacitor. This external capacitor is usually necessary to have acceptable transient response, power supply noise rejection (PSR), and ...
