go into thermal shutdown. For the G915 in the SOT89 package is 250°C/W (See Recommended Minimum

Footprint). The safe operation in SOT 89 package, it can see “Typical Performance Characteristics” (Safe

Operating Area).

Note3: Low duty pulse techniques are used during test to maintain junction temperature as close to ambient as pos-

sible.

Note4: The type of output capacitor should be tantalum, aluminum or ceramic.

Definitions

Dropout Voltage

The input/output Voltage differential at which the regu-

lator output no longer maintains regulation against

further reductions in input voltage. Measured when the

output drops 100mV below its nominal value, dropout

voltage is affected by junction temperature, load cur-

rent and minimum input supply requirements.

Line Regulation

The change in output voltage for a change in input volt-

age. The measurement is made under conditions of low

dissipation or by using pulse techniques such that av-

erage chip temperature is not significantly affected.

Load Regulation

The change in output voltage for a change in load

current at constant chip temperature. The measure-

ment is made under conditions of low dissipation or by

using pulse techniques such that average chip tem-

perature is not significantly affected.

Maximum Power Dissipation

The maximum total device dissipation for which the

regulator will operate within specifications.

Quiescent Bias Current

Current which is used to operate the regulator chip

and is not delivered to the load.
