Back on-line with home made power regulator

Here is the MIC5209 with 2 capacitors to form my new 3.3v power regulator

Attached and soldered to the back side of the JY-MCY to power it

This provides 3.3v directly to the power select pin, so I must remove the power selection jumper

This will do for now (fingers crossed).
Back to programming...

Power failure of the 3.3V LDO

My web-server is down with a power failure, so no capturing of temperatures on the coldest spring in UK for years.

The 3.3V voltage regulator on the JY-MCU board is cocked (overloaded).
After investigating the details, looks like I was lucky it worked so far, for more than a month.

The JY-MCU board use the XC6202P332 by TOREX.
This voltage regulator can supply maximum output current of 150mA.
This is more than enough for powering the ATmega32 and LEDs.

However, the ENC28J60 needs up to 180mA to transmit data (120mA to receive).
This is way to much for the XC6202P332 to cope with.

I ordered a more powerful regulator from ICREL, a MIC5209-3.3YS that can source up to 500mA.

Stay tuned for the modified board with the new regulator.
