NotesNotes
4.
The limiting factor is junction temperature; taking into account the power dissipation, thermal resistance, and heat sinking.
5.
Pin soldering temperature limit is for 10 seconds maximum duration. Not designed for immersion soldering. Exceeding these limits may
cause malfunction or permanent damage to the device.
6.
Maximum power dissipation at indicated ambient temperature in free air with no heatsink used.
7.
For TA = 85°C and PD = 700 mW and RθJB = 47°C/W.
8.
Measured with 4 layers 2s2p JEDEC std. PCB.
Table 2. Maximum Ratings (continued)
All voltages are with respect to VIN unless otherwise noted. Exceeding these ratings may cause a malfunction or permanent
damage to the device.
