This high current regulator with low voltage drop was found in the datasheet of the used integrated circuit itself. The transistor accepts an equivalent and must be provided with a heat sink.
This is the circuit for the HM-10ª, an instrument sold by Heathkit. The circuit is from a Radio...
This circuit indicates when the monitored voltage drops below the value determined by the divider...
This circuit, from a 1975 Motorola manual, uses a power Darlington transistor of the time. We can...
