Thermal Resistance (5)
TSOT23-8..............................100..... 55... °C/W

SW...-0.3V (-5V for <10ns) to 17V (19V for 5ns)
Notes:
VBST ........................................................VSW+6V
1) Exceeding these ratings may damage the device.
2) About the details of the EN pin’s ABS MAX rating, please
refer to Page 9, Enable section.
(2)
All Other Pins............................... -0.3V to 6V
(3)
Continuous Power Dissipation (TA = +25°C)
........................................................... 1.25W
Junction Temperature...............................150°C
Lead Temperature ....................................260°C
Storage Temperature................. -65°C to 150°C
3) 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.
Recommended Operating Conditions (4)
Supply Voltage VIN ...........................4.5V to 16V
Output Voltage VOUT............... 0.8V to VIN x DMAX
Operating Junction Temp. (TJ). -40°C to +125°C
4) The device is not guaranteed to function outside of its
operating conditions.
5) Measured on JESD51-7, 4-layer PCB.
