Of course, the original TO-3 regulators were linear and would ... surely has a wider input voltage range and more output current capacity. We’ve seen replacement switching regulators before ...

In fact, this is their main advantage over switching converters, where noise isolation and emissions are major system concerns. The fundamental concept of the linear voltage regulator is shown in ...

This article explains how to extend the battery lifetime of a device by adding a nanopower converter to an existing system, ...

but the linked video also has him using the modules to repair a Commodore 1541 which originally had the linear TO3 voltage regulators. It’s definitely a non-trivial task to build a switching ...

Figure 3 : Efficiency versus input voltage for an inductorless Switching Regulator As portable electronic systems ... Inductorless SRs are not controlled with PWM but with linear regulation and then ...
