7.6 System Characteristics

The following specifications are ensured by design provided that the component values in the typical application circuit are used. These parameters are not ensured by production testing. Limits apply to the recommended operating junction temperature range of –40°C to 150°C, unless otherwise noted. Minimum and Maximum limits are ensured through test, design or statistical correlation. Typical values represent the most likely parametric norm at Tj = 25°C, and are provided for reference purposes only. Unless otherwise stated the following conditions apply: Vin = 13.5 V.

(1) 125°C is worst case temperature for load regulation. Layout is critical since adjustable option does not have an AGND terminal.

(2) See Section 8.3.7 in Section 8 for the meaning of this specification and how it can be calculated.
