TinyLDOP is a breadboard-compatible linear regulator PCB for generating additional low-current voltage rails from a single power supply. It designed to be placed at the middle part of a breadboard as shown:
Specifications
Considering the typical supply voltages of electronic systems, we will set the output voltage range to 1.8 – 12 V.
According to the LM317M datasheet, the difference between input and output voltage can be as low as 2.5 V. Therefore, the input voltage range must be 4.3 – 14.5 V (which we will round to 5 – 15 V)
The maximum output current depends on the input-output voltage difference and the maximum power the device is able to dissipate. Taking into account the worst case: input voltage equal to 15 V, output voltage equal to 1.8 V and considering the package is able to dissipate 750 mW with a small heatsink, the maximum output current is 57 mA, which we will round to 50 mA.
| Specification | Value |
|---|---|
| Input voltage range [V] | 5–15 |
| Output voltage range [V] | 1.8–12 |
| Maximum output current [mA] | 50 |

Questions
How big is the TinyLDOP PCB?
It measures 17.8 × 20.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TinyLDOP use?
10 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the TinyLDOP KiCad files?
From the mtutusaus/TinyLDOP repository on GitHub, at the commit this page was made from: the board is TinyLDOP.kicad_pcb and its schematic TinyLDOP.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TinyLDOP design in my own project?
Its repository states no licence, so its author keeps all rights: ask mtutusaus before reusing the design.
