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 allowable power dissipation is a function of the maximum junction temperature, TJ, the junc-
tion-to-ambient thermal resistance, RθJA, and the ambient temperature, TA. Exceeding the maximum allow-
able power dissipation will cause excessive die temperature, and the regulator will go into thermal shut-
down. Maximum power dissipation can be calculated based on the output current and the voltage drop
across the pass. To determine the maximum power dissipation can use basic equation: PD(max) =TJ (max)-TA/
θ
JA = IOUT (VIN-VOUT) = 800mW. The safe operation of SOT-223 package by G952, it can see “Typical
Performance Characteristics”. (Safe Operation 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 or aluminum.
Definitions
Dropout Voltage
The input/output Voltage differential at which the
regulator 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
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.
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.
