ABSOLUTE MAXIMUM RATINGS
(1)
All pins ……………………............... -0.3V to +6V
Continuous power dissipation (T
A
= +25°C)
(2)
SOIC8………………………… ...... …………1.3W
Junction temperature………… ... …………150°C
Lead temperature ………… ...... …………260°C
Storage temperature………….. -65°C to +150°C
Recommended Operating Conditions
Supply voltage (VCC)
MPQ6411……………………………………… 5V
MPQ6411-33…………………………………3.3V
Operating junction temp. (T
J
) ..... -40°C to 125°C
Thermal Resistance

SOIC-8…..………………………96……45…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 an excessive die temperature, causing
the regulator to go into thermal shutdown. Internal thermal
shutdown circuitry protects the device from permanent
damage.
3) Measured on JESD51-7, 4-layer PCB.
