Recommended Operating Conditions

(3)

Supply Voltage VIN ..............................6V to 60V

Operating Junction Temp. (TJ). -40°C to +125°C

Thermal Resistance

(4)

θJA

θJC

TSOT6 ..................................100 ..... 55 ... °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

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.

3) The device is not guaranteed to function outside of its

operation conditions.

4) Measured on JESD51-7, 4-layer PCB.
