SOT563
ABSOLUTE MAXIMUM RATINGS (1)
Supply voltage (VIN) ....................................... 6V
Thermal Resistance (4) θJA
SOT563………………….......130……60.…°C/W
θJC
V
SW................................-0.6V (-5V for <10ns) to
NOTES:
6V (8V for <10ns or 10V for <3ns)
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 produces an excessive die temperature, causing
the regulator to go into thermal shutdown. Internal thermal
shutdown circuitry protects the device from permanent
damage.
All other pins.....................................-0.3V to 6V
Junction temperature................................150°C
Lead temperature .....................................260°C
(2)
Continuous power dissipation (TA = +25°C)
……….….. .................................................... 1W
Storage temperature................ -65°C to +150°C
Recommended Operating Conditions (3)
Supply voltage (VIN) ........................2.3V to 5.5V
Operating junction temp. (TJ)... -40°C to +125°C
3) The device is not guaranteed to function outside of its
operating conditions.
4) Measured on JESD51-7, 4-layer PCB.
