NOTES:
1. At Tj ≥ 150°C a thermal switch reduces the output current to avoid damage.
2. Recommended load capacitors: In every case CREG1 = CREG2 = 100nF to ground with series resistance ≤0.1Ω. Additional capacitor
optional ≤1000µF with series resistance ≤5Ω. The low series resistance is very important to ensure regulator stability.
3. Standard deviations are based on the characterization results of 90 ICs.
