− | When I began experimenting with embedded processors, I found that many needed supplies in the 3V to 4V range. By this time I had become fairly adept at using the 723 and since I had some still, I decided to use one, rather than investing in a fixed low voltage regulator. | + | When I began experimenting with embedded processors, I found that many needed supplies in the 3V to 4V range. By this time I had become fairly adept at using the 723 and since I had some still, I decided to use one, rather than investing in a fixed low voltage regulator. I went with a positive output using an external PNP transistor. Again, I added a trimmer pot, so I can adjust from around 2.75V to 4.25V. This little board (the transistor has a TO92 package) measures only 1" x 2" and has a power on LED indicator, and two–2-pole screw terminal blocks. It has been very handy. |
