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

≈ Tj, data other than the output voltage/temperature coefficient

does not include fluctuations due to temperature variations.
