General Description
The G1084 is a low dropout linear regulator with a
dropout of 1.2V at 5A of load current. It is avail-
able in an adjustable version, which can set the
output from 1.25V to 5V with only two external
resistors.
The G1084 provides over temperature and over
current protection circuits to prevent it from being
damaged by abnormal operating conditions.
The G1084 is available in TO-220, TO-252, TO-263
and TO-263T packages. A minimum of 220µF
tantalum electrolytic capacitor is required at the
output to improve the transient response and sta-
bility.

Definitions
Output Voltage
The G1084 provides an adjustable output voltage from
1.25V to 5V. with two external resistors. It can be for-
mulated as:
VOUT = 1.25V x (1+
IADJ = 80µA (TYP.)
R2
R1
) + IADJ x R2
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 2% 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.
