The TL1963A-xx regulators are tested and specified under pulse load conditions such that TJ ≉ TA. They are fully tested at TA = 25°C.

Performance at –40 and 125°C is specified by design, characterization, and correlation with statistical process controls.

(2) Typical values represent the likely parametric nominal values determined at the time of characterization. Typical values depend on the

application and configuration and may vary over time. Typical values are not ensured on production material
