Sigma22 discrete linear regulated power supply

Overview

Following the positive and negative voltages, this small heat sink can carry 1-2a current, and the mos is not very sensitive to heat.
I sell this in my own Taobao store, you can see the Taobao link, but there’s nothing much to say https://item.taobao.com/item.htm?ft=t&id=694517954996
It’s just a discrete linear power supply.
The input can be dual AC 9-25v, and the output voltage difference is about 5-7v. Just leave a good voltage difference for the target output voltage.

【Help】Expert help please!!! Urgent!!!!!!!!!
I use MOS tube IRF9630 as power switch tube, and the load is M22 module (I wonder if you have used this?)!!!When the module detects the SIM card, the output voltage of the MOS tube is very unstable!!!
mspdebug issue with msp430f5529lp
I'm really annoyed. I don't have to use mspgcc when I have CCS. Now I'm stumped at the beginning. The problem is as follows: $mspdebug rf2500 The result prompt is: usbutil: unable to find a devcie mat
Dear Beaglebone players, what cape do you need?
[size=5]There are very few BBB capes available in China. I would like to ask what capes you want. [/size] Attached is the official cape list [url]http://elinux.org/Beagleboard:BeagleBone_Capes[/url]

What do you think is a valuable life?
I saw someone said it was very good. In life, nothing goes as planned, and in life, nothing goes as planned. In fact, everyone has a hard time, with countless difficulties and unspeakable grievances.
Urgent!!! How to put large components into the user store???
I saw a friend's blog saying: Put some large components (such as Chinese characters) libraries into the user store (such as SD card, Flash, etc.) to reduce the kernel size. This is also a good idea. W
