6.3 Recommended Operating Ratings

See note(1)
Supply Voltage Range (VIN) 4.5V to 42V
Junction Temperature Range (TJ) −40°C to +125°C
Thermal Resistance (θJA) 28-ball DSBGA(2) 50°C/W
For soldering specifications see SNOA549
(1) Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which operation of the device is intended to be functional. For ensured specifications and test conditions, see Electrical Characteristics .
(2) θJA calculations were performed in general accordance with JEDEC standards JESD51–1 to JESD51–11.
