Ampere or Current Booster Circuit

Monday, June 14th, 2010

Small and very useful circuit, Can be built on a veroboard
Volt regulators such as the LM708, and LM317 series (and others) sometimes need to provide a little bit more current then they actually can handle. If that is the case, this little circuit can help out. A power transistor such as the 2N3772 or similar [...]


Current Expanded Regulated Power Supply

Monday, May 10th, 2010

Actually, this is ordinary regulated power supply, but the current expander using a transistor make this power supply become powerful.

Based on the datasheet, the stabilizer IC’s can deliver up to 1A output current. For example 78xx series regulators are available in different voltage ratings, but in any case the current should not exceed 1A.
The transistor [...]


5V High Current Regulated Circuit

Thursday, February 11th, 2010

Since receiving the 3-pin ICS market regulator, the issue of designing circuits accumulation ability has made under and under discussion. However, new ICS aforementioned types of circuits absolute actuality ability amusement born in laboratories at about 1 ampere units. In addition, skills are necessary stages, because the air received (5A or 10A) ICS are current [...]
