ABSOLUTE MAXIMUM RATINGS (1)
VIN ..................................................-0.3V to 17V
Thermal Resistance (4)
TSOT-23-6.............................100..... 55... °C/W
θJA
θJC
V
SW......................................................................
-0.3V (-5V for <10ns) to 17V (19V for <10ns)
BS .........................................................VSW+6V
Notes:
1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of the
maximum junction temperature TJ (MAX), the junction-to-
ambient thermal resistance θJA, and the ambient temperature
TA. The maximum allowable continuous power dissipation at
any ambient temperature is calculated by PD (MAX) = (TJ
(MAX)-TA)/θJA. Exceeding the maximum allowable power
dissipation will cause excessive die temperature, and the
regulator will go into thermal shutdown. Internal thermal
shutdown circuitry protects the device from permanent
damage.
