G915
1.5V 600mA Low Dropout Regulator
Features
General Description
Wide Input Voltage Range 2.9V~6V
The G915 positive 1.5V voltage regulator features the
ability to source 600mA of output current. A low qui-
escent current is provided. The typical quiescent cur-
rent is 0.3mA.
Output Current in Excess of 600mA
Output Voltage Accuracy ±2%
Quiescent Current, Typically 0.3mA
Internal Short Circuit Current Limit
Internal Over Temperature Protection
Familiar regulator features such as over temperature
and current limit protection circuits are provided to pre-
vent it from being damaged by abnormal operating
conditions.

Over Temperature
Over Temperature Hysterics
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 guaran-
teed 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 150°C and IC will
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).
Note 1:
Note2:
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, aluminum or ceramic.

Note4:
Definitions
Dropout Voltage
Load Regulation
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.
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
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 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.
Quiescent Bias Current
Current which is used to operate the regulator chip
and is not delivered to the load.
