Lad402p Schematic Top ((link)) Jun 2026

| Symbol | Part | Typical Value | Function | |--------|------|---------------|----------| | | Upper Divider Resistor | 2.2 kΩ – 5 kΩ | Works with R3 to set Vout = Vref × (1 + R2/R3). Vref for LAD402P ≈ 1.2 V. | | R3 | Lower Divider Resistor | 1 kΩ – 2.2 kΩ | Together with R2 defines the output voltage. | | C2 | Compensation Capacitor | 0.1 µF – 1 µF | Placed from the feedback node (junction of R2/R3) to ground; adds phase margin and reduces output ripple. | | R4 (optional) | Load‑Adjust Resistor | 10 Ω – 100 Ω | Small resistor in series with the load to improve transient response; not required in the reference design. |

Often included near the start, this diagram shows how the main power source (Battery or DC Jack) is stepped down into various voltage rails like to power different parts of the board. System Architecture: lad402p schematic top

with a pull-up to ensure Arduino high-voltage thresholds are reliably met. Sequencing Relays (G5LE-1A) driven by Darlington arrays allow safe 10-channel switching. | Symbol | Part | Typical Value |
