TSOT23-6 QFN8 (2mm x 2mm)
ABSOLUTE MAXIMUM RATINGS
(1)
SW , OV Pins................................–0.5V to +28V
All Other Pins..............................–0.3V to +6.5V
Continuous Power Dissipation (T

IN
to 25V
Operating Junction Temp. (T

TSOT23-6 ..............................220 .... 110.. °C/W
QFN8 (2mm x 2mm) ...............80 ...... 16 ... °C/W
Notes:
1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of the
maximum junction temperature T
J
(MAX), the junction-to-
ambient thermal resistance θ
JA
, and the ambient temperature
T
A
. The maximum allowable continuous power dissipation at
any ambient temperature is calculated by P
D
(MAX) = (T
J
(MAX)-T
A
)/θ
JA
. Exceeding the maximum allowable powe
dissipation will cause excessive die temperature, and the
regulator will go into thermal shutdown. Internal thermal
shutdown circuitry protects the device from permanent
damage.
3) The device is not guaranteed to function outside of its
operating conditions.
4) Measured on JESD51-7, 4-layer PCB.
