Orderable Information

5.1 Absolute Maximum Ratings

over operating free-air temperature range (unless otherwise noted)(1)
MIN MAX UNIT
VIN Unregulated input –0.3 42 V
VOUT Regulated output –0.3 VIN + 0.3V(2) V
Delay Reset delay input,  power-good adjustable threshold –0.3 6 V
PG Power-good output –0.3 20 V
TJ Operating junction temperature –40 150 °C
Tstg Storage temperature –65 150 °C
(1) Operation outside the Absolute Maximum Ratings may cause permanent device damage. Absolute Maximum Ratings do not imply functional operation of the device at these or any other conditions beyond those listed under Recommended Operating Conditions. If used outside the Recommended Operating Conditions but within the Absolute Maximum Ratings, the device may not be fully functional, and this may affect device reliability, functionality, performance, and shorten the device lifetime
(2) The absolute maximum rating is VIN + 0.3V or 20V, whichever is smaller
