A buck converter drop in replacement for TO-220 LDOs
There are currently two versions:
- One for 78xx series LDOs
- One for the LM1117 LDO
They are both configured for 3.3V, but replacing R3 allows the output voltage to be set.
| Output Voltage | R3 Value |
|---|---|
| 1.5V | 86k6 |
| 1.8V | 60k4 |
| 2.5V | 35k7 |
| 3.3V | 24k3 |
| 5.0V | 14k3 |
| 12V | 5k36 |
| 24V | 2k61 |
Please take note of the pinouts as seen in the renders.
I've been able to test basic functionality of both boards, but I am currently working on extended testing.
