BETAWire the physical leads
With the marking toward you, the left, middle and right leads are ADJ, OUT and IN.

Build a basic LM350 circuit with labeled pins, component values and connection guidance.
LM350 in a circuit
A physical TO-220 regulator with a feedback divider and a modest load.
Connect it, step by step
Follow the component values and pin connections
Add the divider and load
110 Ω from OUT to ADJ and 330 Ω from ADJ to ground set nominal 5 V; the 50 Ω load draws about 100 mA.
Check dissipation
The nominal pass-stage loss is about 0.45 W here. Recalculate before increasing voltage or current.
