LT1083 Adjustable Linear Power-Supply DIY Kit

Build a variable DC supply stage for a suitable electronics project. This LT1083 kit combines rectification, filtering and an adjustable regulator. It is for makers who can assemble and verify a circuit before applying a load.

• ✅ Set a project supply voltage — A potentiometer adjusts the regulator output.
• ✅ Build the circuit yourself — A kit format provides an assembly project.
• ✅ Fit a small bench assembly — The board has a compact footprint.
• ✅ Use a suitable low-voltage source — AC or DC input ranges are described.

Plan heat dissipation and input headroom

The stated 7A figure is a maximum label, not a promise across every input/output combination. Linear regulation generates heat, so actual current depends on cooling, voltage drop and the component limits.

The circuit is not a complete chemistry-aware battery charger. A battery-charging application needs an appropriate current and voltage control design. Verify assembly, polarity and output before connecting equipment.
