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
G952 in SOT-89 package. θJA is 173°C/W For the G952 in SOT-223 package, θJA is 148°C/W, in TO-252 package, θJA
is 124°C/W. (See recommend minimum footprint). The safe operation in SOT- 89, SOT-223, TO-252 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.

Definitions
Dropout Voltage
Load Regulation
The input/output Voltage differential at which the regulator
output no longer maintains regulation against further re-
ductions in input voltage. Measured when the output drops
100mV below its nominal value. Dropout voltage is af-
fected by junction temperature, load current and minimum
input supply requirements.
The change in output voltage for a change in load current
at constant chip temperature. The measurement is made
under conditions of low dissipation or by using pulse tech-
niques such that average chip temperature is not signifi-
cantly affected.
Maximum Power Dissipation
Line Regulation
The maximum total device dissipation for which the regu-
lator will operate within specifications.
The change in output voltage for a change in input voltage.
The measurement is made under conditions of low dissi-
pation or by using pulse techniques such that average chip
temperature is not significantly affected.
Quiescent Bias Current
Current which is used to operate the regulator chip and is
not delivered to the load.
