This circuit is from Motorola documentation, but can be implemented with virtually any phototransistor and any general-purpose transistor. The supply voltage can also be changed.
The advantage of this circuit lies in the fact that it does not need a negative source to generate...
We found this circuit in the Linear Applications Handbook of the 1994 National Semiconductor. The...
This regulated power supply can provide currents up to 1 A to a load. The transformer may actually have...
