Note 1. Stresses listed as the above “Absolute Maximum Ratings” may cause permanent damage to the

device. These are for stress ratings. Functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may remain possibility to affect device reliability.

Note 2. Devices are ESD sensitive. Handling precaution recommended. Note 3. θJA is measured in the natural convection at TA=25°C on a high effective thermal conductivity

test board (4 Layers, 2S2P) of JEDEC 51-7 thermal measurement standard.

Note 4. The device is not guaranteed to function outside its operating conditions. Note 5. The dropout voltage is defined as VIN - V

Application Information

Thermal Considerations

Although internal thermal limiting function is

P (MSOT-23)

= (125°C - 25°C)/263 = 380mW

D(MAX)

integrated in GS7118, continuously keeping the junction near the thermal shutdown temperature may possibly affect device reliability. For continuous operation, it is highly recommended to keep the junction temperature below the maximum operation junction temperature 125°C for maximum reliability. The power dissipation definition in device is: PD = (VIN - V

OUT

) x I

+ VIN x IQ

OUT

The maximum power dissipation depends on the thermal resistance of IC package, PCB layout, the rate of surroundings airflow and temperature difference between junction to ambient. The maximum power dissipation can be calculated by following formula: P Where T

D(MAX)

= ( T

J(MAX)

- TA ) / θJA

J(MAX)

is the maximum operation junction temperature 125°C, TA is the ambient temperature and the θJA is the junction to ambient

P

= (125°C - 25°C)/333 = 300mW

D(MAX)

(SOT-353) P

= (125°C - 25°C)/250 = 400mW

D(MAX)

(TSOT-23-5) P

= (125°C - 25°C)/250 = 400mW

D(MAX)

(SOT-23-5) P

= (125°C - 25°C)/182 = 571mW

D(MAX)

(SOT-89-3) P

= (125°C - 25°C)/75 = 1333mW

D(MAX)

(PSOP-8) P

= (125°C - 25°C)/135 = 741mW

D(MAX)

(SOT-223) P

= (125°C - 25°C)/68 = 1471mW

D(MAX)

(TO-252) P

= (125°C - 25°C)/278 = 360mW

D(MAX)

(TDFN4-1x1.2) The maximum power dissipation depends on operating ambient temperature or fixed T

J(MAX)

and thermal resistance θJA. For GS7118 thermal resistance. For recommended operating conditions specification of GS7118, where T

J(MAX)

is the

maximum junction temperature of the die (125°C)

packages, the Figure 4. of derating curves allows

the designer to see the effect of rising ambient

temperature on the maximum power allowed.

and TA is the maximum ambient temperature. The junction to ambient thermal resistance (θJA is layout dependent) for SOT-23-3 package is 250°C/W ,MSOT-23 package is 263°C/W and SOT-323 package is 333°C/W on standard JEDEC 51-3 thermal test board. The maximum power dissipation at TA = 25°C can be calculated by following formula: P

= (125°C - 25°C)/250 = 400mW
