G930/G931
3.5V 400mA Low Dropout Regulator
Features
General Description
ꢀDropout voltage typically 0.8V @ IO = 400mA
ꢀOutput current in excess of 400mA
ꢀOutput voltage accuracy +3%/-2%
ꢀQuiescent current, typically 600µA
ꢀInternal short circuit current limit
ꢀInternal over temperature protection
The G930/G931 positive 3.5V voltage regulator fea-
tures the ability to source 400mA of output current
with a dropout voltage of typically 0.8V over the en-
tire operating temperature range. A low quiescent
current is provided over the entire output current
range. The typical quiescent current is 0.6mA. Fur-
thermore, the quiescent current is smaller when the
regulator is in the dropout mode (VIN < 3.5V).
Familiar regulator features such as over temperature
and over current protection circuits are provided to
prevent it from being damaged by abnormal operating
conditions.

Note 1:
Note2:
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.
The maximum power dissipation is a function of the maximum junction temperature, TJmax ; total thermal re-
sistance, θJA, and ambient temperature TA. The maximum allowable power dissipation at any ambient tem-
perature is Tjmax-TA / θJA. If this dissipation is exceeded, the die temperature will rise above 130°C and IC
will go into thermal shutdown. For the G930/G931 in SOT 89 package, θJA is 250°C/W. (See Recom-
mended Minimum Footprint). The safe operation in SOT 89, it can see “Typical Performance Characteris-
tics” (Safe Operating Area).
Note3:
Note4:
Low duty pulse techniques are used during test to maintain junction temperature as close to ambient as pos-
sible.
The type of output capacitor should be tantalum or aluminum.
Load Regulation
Definitions
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.
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.
Maximum Power Dissipation
The maximum total device dissipation for which the
regulator will operate within specifications.
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.
Quiescent Bias Current
Current which is used to operate the regulator chip
and is not delivered to the load.
