APPLICATION INFORMATION

The SPX29300/01/02/03 incorporates protection against over-current faults, reversed load insertion, over temperature operation, and positive and negative transient voltage.

Thermal Considerations

Although the SPX29300/01/02/03 offers limiting 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.

TO-220 Design Example:

Assume that V

= 10V, V

IN

OUT

= 5V, I

OUT

=

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

θCH= case to heatsink thermal

resistance

θJC = junction to case thermal

resistance The power calculated under these conditions is:

PD = (VIN – V

OUT

) * I

= 7.5W.

OUT

And the junction temperature is calculated as

TJ = TA + PD * (θHA + θCH + θJC) or 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 aluminum capacitor will guarantee stability over all load conditions. A tantalum capacitor is recommended if a faster load transient

response is needed. If the power source has a high AC impedance, a 0.1µF ceramic capacitor between input & ground is recommended.

Minimum Load Current

To ensure a proper behavior of the regulator under light load, a minimum load of 5mA for SPX29300/01/02/03 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).

Error Flag

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.

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.

Typical Application Circuits

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:

V

OUT =VREF

* [1 + (R1/R2)]. For best results, the total series resistance should be small enough to pass a minimum regulator load current of 5 mA. A minimum value of 10kohms is recommended for R2 with a range between 10kohms and 47 kohms.
