DESCRIPTION
The SPX29300/01/02/03 are 3A, highly accurate voltage regulators with a low drop out
voltage of 450mV dropout (typical) @ 3A. These regulators are specifically designed for low
voltage applications that require a low dropout voltage and a fast transient response. They
are fully fault protected against over-current, reverse battery, and positive and negative
voltage transients. On-Chip trimming adjusts the reference voltage to 1% initial accuracy.
Other features in the 5 pin versions include Enable, and Error Flag.
The SPX29300/01/02/03 are offered in 3 & 5-pin TO-220 & TO-263 packages. For a 1.5A
version, refer to the SPX29150 data sheet.

NOTES:
Note 1: Maximum positive supply voltage of 20V must be of limited duration (<100ms) and duty cycle of less than 1%. The maximum continuous supply
voltage is 16V.
Note 2: Full load current (I ) is defined as 3.0A.
FL
Note 3: Dropout voltage is defined as the input to output differential when the output voltage drops to 99% of its nominal value.
Note 4: V = V
+1V. For example, use V = 4.3V for a 3.3V regulator. Employ pulse-testing procedures to minimize temperature rise.
IN
OUT (NOMINAL)
IN
Note 5: Ground pin current is the regulator quiescent current. The total current drawn from the source is the sum of the load current to the ground current.
Note 6: Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range
Note 7: Thermal regulation is defined as the change in output voltage at time T after a change in power dissipation is applied, excluding load / line regulation effects.

Note 9: Comparator threshold is expressed in terms of a voltage differential at the Adjust terminal below the nominal reference voltage measured 6V input. To
express these thresholds in terms of output voltage change, multiply the error amplifier gain = V /V = (R1 + R2)/R2. For example, at a programmable

output voltage of 5V, the Error output is guaranteed to go low when the output drops by 95mVx 5V/ 1.240V = 38mV. Threshold remain constant as a percent of

APPLICATION INFORMATION
The SPX29300/01/02/03 incorporates pro-
tection against over-current faults, reversed
load insertion, over temperature operation, and
positive and negative transient voltage.
response is needed. If the power source has a
high AC impedance, a 0.1μF ceramic capacit-
or between input & ground is recommended.
Minimum Load Current
Thermal Considerations
To ensure a proper behavior of the regulator
under light load, a minimum load of 5mA for
SPX29300/01/02/03 is required.
Although the SPX29300/01/02/03 offers lim-
iting circuitry for overload conditions, it is still
necessary to insure that the maximum junction
temperature is not exceeded in the application.
Heat will flow through the lowest resistance
path, the junction-to-case path. In order to
insure the best thermal flow of the component,
proper mounting is required.
Adjustable Regulator Design
The SPX29302/03 are adjustable regulators
that can be programmed to any value between
1.25V and 16V using 2 resistors, R1 and R2.
The relationship between the resistors is:
R1 = R2(Vout/1.240-1).
TO-220 Design Example:
Assume that VIN = 10V, VOUT = 5V, IOUT
=
Error Flag
1.5A, TA = 50°C, θHA= 1°C/W, θCH= 2°C/W,
and θJC= 3C°/W, where:
TA = ambient temperature,
θHA= heatsink to ambient thermal
resistance
The SPX29301/03 features an error flag that
indicates either an over current or under
voltage condition. The flag output goes low,
sinking 10mA when either condition occurs.
θCH= case to heatsink thermal
resistance
θJC = junction to case thermal
resistance
Enable Input
The SPX29301/02 have an Enable function
that switches the regulator on and off. Their
thresholds are TTL compatible. When the
regulator is active, approximately 20 uA flows
through the Enable pin.
The power calculated under these conditions
is:
PD = (VIN – VOUT) * IOUT = 7.5W.
Typical Application Circuits
And the junction temperature is calculated as
TJ = TA + PD * (θHA + θCH + θJC) or
TJ = 50 + 7.5 * (1+2+3) = 95°C
Figure 1 represents at typical fixed output
regulator. Figure 2 represents an adjustable
output regulator. The values of R1 and R2 set
the output voltage value as follows:
VOUT =VREF * [1 + (R1/R2)].
Reliable operation is insured.
A minimum value of 10kohms is recommen-
ded for R2 with a range between 10kohms and
47 kohms.
Capacitor Requirements
The output capacitor is needed to insure sta-
bility and minimize the output noise. The value
of the capacitor varies with the load. However,
a minimum value of 10μF aluminum capacitor
will guarantee stability over all load conditions.
A tantalum capacitor is recommended if a faster
load transient
