Picaxe power supply question. I have powered all of my previous projests from either 3x AA alkaline batteries in series; or a 9vdc wall wart through an off-the-shelf “buck boost” module. These have worked reliably with no problems. In order to move-on I have made a 5vdc regulator using the attached circuit from the Picaxe manual . I am using a 9vdc 300 mA wall wart. The regulator chip is an LM7805C; and the supply output is 5.6vdc (with a load consisting of a yellow Led & 330 ohm resistor ).
Is this typical?? Is it safe to use this supply to power my project (project draws about 120 mA and consists of an 08M2; a Picaxe 133Y serial OLED display; a PIR; and a Picaxe ERF module )?
Thank you, JimS
