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 0.1. Additional capacitor
optional 1000µF with series resistance 5. The low series resistance is very important to ensure regulator stability.
3. Standard deviations are based on the characterization results of 90 ICs.
