Note: This IC is not designed to be radiation-resistant.
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 â Tj, data other than the output voltage/temperature coefficient
does not include fluctuations due to temperature variations.
