Note: All characteristics are measured with 0.33 µF and 0.1 µF capacitors connected to input and output pins, respectively. Because measurements (pulse measurements) were taken when Ta ≈ Tj, data other than the output voltage/temperature coefficient does not include fluctuations due to temperature variations. |
