Electrical Characteristics (Continued)
For typical values, TA=25°C and VIN=12V. For min. and max. values, TA is the operating ambient temperature range
with -25°C ≤ TA ≤ 85°C and 5V ≤ VIN ≤ 25.5V, unless otherwise specified. Specifications from -25°C to 85°C are guar-
anteed by design based on final characterization results.
