How big is a typical board using the 78L05 (SOT-89, Vin ≤30V)?
The median is 22.9 × 74.9 mm, and 100% are two-layer designs.
What is the most popular open source board using the 78L05 (SOT-89, Vin ≤30V)?
By GitHub stars, MPBCH32M030DS0 power board B by ghostinkoma, with 0 stars.
Can I simulate one of these boards using the 78L05 (SOT-89, Vin ≤30V) before building it?
Yes. HardLabs turns a board's netlist and BOM into a working simulation, so you can boot and test firmware against it with no hardware on your desk.
