7.5 Electrical Characteristics (continued)

Limits apply over the recommended operating junction temperature range of -40°C to +125°C, unless otherwise noted.

Minimum and Maximum limits are specified 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 = 12. VIN1 shorted to VIN2 = VIN. VOUT is output set point.
