Note 1: Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Conditions are
conditions under which the device functions but the specifications might not be guaranteed. For guaranteed specifications
and test conditions see the Electrical Characteristics.
Note2: The maximum power dissipation is a function of the maximum junction temperature, TJmax ; total thermal resistance, θJA,
and ambient temperature TA. The maximum allowable power dissipation at any ambient temperature is Tjmax-TA / θJA. If
this dissipation is exceeded, the die temperature will rise above 150°C and IC will go into thermal shutdown. For the
G905 in SOT-89 (T2) package, θJA is 173°C/W (See recommend 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 possible.
Note4: The type of output capacitor should be tantalum or aluminum.

Load Regulation
Dropout Voltage
The change in output voltage for a change in load
The input/output Voltage differential at which the regu-
current at constant chip temperature. The measure-
lator output no longer maintains regulation against

further reductions in input voltage. Measured when the

output drops 100mV below its nominal value, dropout
perature is not significantly affected.
voltage is affected by junction temperature, load cur-
rent and minimum input supply requirements.
Maximum Power Dissipation
Line Regulation
The maximum total device dissipation for which the
regulator will operate within specifications.
The change in output voltage for a change in input
voltage. The measurement is made under conditions
of low dissipation or by using pulse techniques such
that average chip temperature is not significantly af-
fected.
Quiescent Bias Current
Current which is used to operate the regulator chip
and is not delivered to the load.
