Abstract
A stabilized power supply circuit has a stabilized or regulator circuit connected between an input terminal and a first output terminal and a constant voltage element for example, a Zener diode, whose one electrode is connected to the input terminal and whose other electrode is connected to the first output terminal, and a second output terminal is connected to the first-mentioned electrode of the constant voltage element.
Claims3
A stabilized power supply circuit, comprising:
- a. an input terminal for receiving a DC voltage;
- b. a first output terminal for supplying a first stabilized output voltage;
