          -### 🔧 Common Use Cases

          -

          -#### 1. 🛡️ Inrush Current Limiting

          -- **Function:** When power is first applied, capacitors (especially large filter caps) can draw a big inrush current.

          -- **The 300Ω resistor** slows the charging rate of the input capacitor.

          -- Helps protect:

          -  - Transformer

          -  - Diodes (in rectifier)

          -  - LM317 itself

          -

          -#### 2. 🔥 Power Dissipation / Pre-Regulation

          -- **Drops excess voltage** before it hits the LM317

          -- Reduces the **heat load on the LM317**, especially if there's a large **Vin − Vout** difference.

          -

          -For example:

          -```

          -Vin = 24V, Vout = 12V, Load = 50mA

          -→ Voltage drop across LM317 = 12V

          -→ Power = 12V × 0.05A = 0.6W (hot!)

          -

          -Insert a 300Ω resistor:

          -  V = I × R = 0.05A × 300Ω = 15V drop before LM317

          -  New Vin = 24V − 15V = 9V → not enough

          -  So you may adjust value to drop just a few volts

          -```

          -

          -- You must ensure **enough voltage remains** after the resistor so that LM317 operates normally (requires at least **Vin ≈ Vout + 2V**).
