DESCRIPTION
The SPX29150/51/52/53 are 1.5A, highly accurate voltage regulators with a low dropout
voltage of 390mV (typical) @ 1.5A. These regulators are specifically designed for low volt-
age 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 SPX29150/51/52/53 is offered in 3-pin and 5-pin TO-220 & TO-263 packages. For a 3A
version, refer to the SPX29300 data sheet.

NOTES:
Note 1: Dropout voltage is defined as the input to output differential when the output voltage drops to 99% of its nominal value.
Note 2: Vin = vout (NOMINAL) +1V. For example, use Vin = 4.3V for a 3.3V regulator. Employ pulse-testing procedures to minimize temperature rise.
Note 3: 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 4: Thermal regulation is defined as the change in the output voltage at a time T after a change in power dissipation is applied, excluding load or line
regulation effects.
Note 5: 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 = Vout/vref = (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. Thresholds
remain constant as a percent of Vout as Vout is varied, with the dropout warning occurring at typically 5% below nominal, 7.7% guaranteed.
Note 6: Ven ≤ 0.8V and Vin ≤ 16V, Vout = 0.
Note 7: Maximum positive supply voltage of 20V must be of limited duration (<100m_) < 1%. The maximum continuous supply voltage is 16V.
Note 8: Vref ≤ Vout ≤ (Vin-1), 2.5V≤Vin ≤ 16V, 10mA ≤ Il ≤ Ifl, Tj < Tjmax.

APPLICATION INFORMATION
The SPX29150/51/52/53 incorporates pro-
tection against over-current faults, reversed
load insertion, over temperature operation,
and positive and negative transient volt-
ages.
Tj = 50 + 7.5 * (1+2+3) = 95°C
Reliable operation is insured.
Capacitor Requirements
The output capacitor is needed to insure
stability and minimize the output noise. The
value of the capacitor varies with the load.
However, a minimum value of 10µF alumi-
numcapacitorwillguaranteestabilityoverall
load conditions. Atantalum capacitor is rec-
ommendedifafasterloadtransientresponse
is needed. If the power source has a high
AC impedance, a 0.1µF ceramic capacitor
between input & ground is recommended.
The output capacitors maximum ESR value
for stable operation is 0.33ohms.
Thermal Considerations
Although the SPX29150/51/52/53 offers
limiting circuitry for overload conditions, it is
still necessary to insure that the maximum
junction temperature is not exceeded in the
application.Heatwillflowthroughthelowest
resistance path, the junction-to-case path.
In order to insure the best thermal flow of
thecomponent,propermountingisrequired.
Consult the heatsink manufacturer for ther-
mal resistance and heat sink design.
Minimum Load Current
TO-220 Design Example:
To ensure proper behavior of the regulator
under light loads, a minimum load of 5mA
for SPX29150/51/52/53 is required.
Assume that Vin = 10V, Vout = 5V, Iout =
1.5A, Ta = 50°C, θh= 1°C/W, θch= 2°C/W,
and θjc= 3C°/W, where:
Ta = ambient temperature,
Typical Application Circuits
θha = heatsink to ambient thermal resis-
Figure 19 represents a typical fixed output
regulator. Figure20representsanadjustable
output regulator. The values of R1 and R2
set the output voltage value as follows: Vout
=vref * [1 + (R1/R2)]. A minimum value of
10kΩ is recommended for R2 with a range
between 10kΩ and 47kΩ.
tance
θch = case to heatsink thermal resistance
θjc = junction to case thermal resistance
The power calculated under these condi-
tions is:
Pd = (Vin – vout) * Iout = 7.5W.
And the junction temperature is calculated
as
Tj = Ta + Pd * (θha + θch + θjc) or
