3 / 8 page ![]() Electrical Characteristics for LM9076–5.0 (Continued) The following specifications apply for V IN = 14V; V SHUTDOWN = Open; ILOAD = 10mA; TA = +25˚C; COUT = 10µF, 0.5 Ω < ESR < 4.0 Ω; unless otherwise specified. Bold Values indicate −40˚C ≤ T A ≤ 125˚C.

Note 2: Operating Ratings indicate conditions for which the device is intended to be functional, but does not guarantee specific performance limits. For guaranteed specifications and conditions refer to the Electrical Characteristics Note 3: Not Production tested, Guaranteed by Design. Minimum, Typical, and/or Maximum values are provided for informational purposes only. Note 4: Pulse testing used maintain constant junction temperature (TJ ). Note 5: The regulated output voltage specification is not guaranteed for the entire range of VIN and ouput loads. Device operational range is limited by the maximum junction temperature (T J ). The junction temperature is influenced by the ambient temperature (T A ), package selection, input voltage (VIN ), and the output load current. When operating with maximum load currents the input voltage and/or ambient temperature will be limited. When operating with maximum input voltage the load current and/or the ambient temperature will be limited. Note 6: Worst case (FREE AIR) per EIA/JESD51–3. www.national.com 3 |
