Lad402p Schematic Top [ 480p 2026 ]

: Small brown components (PC) near the CPU or charging IC that may crack or short to ground.

| Symptom | Likely Cause | Quick Test | |---------|--------------|------------| | | Vin not reaching the regulator, or D1 is open. | Measure Vin at the regulator pin; check diode forward voltage with a multimeter. | | Output voltage too low | R2/R3 values wrong, or C2 missing causing instability. | Verify resistor values with a DMM; add a temporary 0.1 µF capacitor at the feedback node. | | Oscillation / high ripple | Inadequate output decoupling, too low C2, or missing ground plane. | Scope Vout while toggling load; add bulk capacitor (47 µF) near the output. | | Thermal shutdown (regulator gets hot, then cuts off) | Over‑current condition, insufficient heat sinking, or Vin‑Vout > 0.5 V at 2 A. | Touch the regulator (carefully) after a brief load; if hot, improve heat sink or lower load. | | Short‑circuit detection not triggering | External sense resistor too low or omitted; internal limit disabled (rare). | Insert a 0.33 Ω resistor in series with the load; verify that Vout drops under heavy load. | lad402p schematic top
