3.3 Output Stage & Load Protection

| Symbol | Part | Typical Value | Function | |--------|------|---------------|----------| | C2 (already covered) | Output Decoupling | See above | Keeps the output stable under rapid load changes. | | R5 (optional) | Output Sense Resistor | 0.1 Ω – 0.33 Ω, 2 W | Allows you to monitor the current via a sense voltage (V = I×R). Helpful for building a secondary over‑current alarm. | | D2 (optional) | Flyback Diode (if driving inductive loads) | 1N5819 or Schottky | Protects the regulator from voltage spikes generated by inductive loads such as motors or solenoids. | | Thermal Pad | Exposed heat‑sink tab | – | Must be soldered to a copper area or a dedicated heat sink for reliable thermal shutdown operation. | lad402p schematic top
