DESCRIPTION

The SPX1117 is a low power positive-voltage regulator designed to satisfy moderate power

requirements with a cost effective, small footprint solution. This device is an excellent choice for

use in battery-powered applications and portable computers. The SPX1117 features very low

quiescent current and a low dropout voltage of 1.1V at a full load. As output current decreases,

quiescent current flows into the load, increasing efficiency. SPX1117 is available in adjustable

or fixed 1.5V, 1.8V, 2.5V,2.5V, 2.85V, 3.0V, 3.3V and 5V output voltages.

The SPX1117 is offered in several 3-pin surface mount packages: SOT-223, TO-252, TO-220

and TO-263. An output capacitor of 10µF provides unconditional stability while a smaller 2.2µF

capacitor is sufficient for most applications.

APPLICATION INFORMATION

Output Capacitor

To ensure the stability of the SPX1117, an

output capacitor of at least 2.2µF (tantalum or

ceramic) or 10µF (aluminum) is required. The

value may change based on the application

requirements of the output load or temperature

range. The value of ESR can vary based on the

type of capacitor used in the applications to

guarantee stability. The recommended value

for ESR is 0.5Ω or less. A larger value of

output capacitance (up to 100µF) can improve

the load transient response.

Soldering Methods

The SPX1117 SOT-223 package is designed

to be compatible with infrared reflow or

vapor-phase reflow soldering techniques.

During soldering, the non-active or mildly

active fluxes may be used. The SPX1117 die

is attached to the heatsink lead which exits

opposite the input, output, and ground pins.

Hand soldering and wave soldering should be

avoided since these methods can cause

damage to the device with excessive thermal

gradients on the package. The SOT-223

recommended soldering method are as

follows: vapor phase reflow and infrared

reflow with the component preheated to within

65°C of the soldering temperature range.

Ripple Rejection

Thermal Characteristics

Ripple rejection can be improved by adding a

capacitor between the ADJ pin and ground as

shown in Figure 23. When ADJ pin bypassing

is used, the value of the output capacitor re-

quired increases to its maximum. If the ADJ pin

isnotbypassed, thevalueoftheoutputcapacitor

can be lowered to 10µF for an electrolytic alu-

minum capacitor or 2.2µF for a ceramic or solid

tantalum capacitor (Fig 22).

The thermal resistance of SPX1117 (SOT-223

Package) is 15°C/W from junction to tab and 31

°C/W from tab to ambient for a total of 46 °C/W

fromjunctiontoambient(Table1).TheSPX1117

features the internal thermal limiting to protect

the device during overload conditions. Special

care needs to be taken during continuous load

conditionssuchthatthemaximumjunctiontem-

perature does not exceed 125 °C. Thermal pro-

tection is activated at >155°C and deactiviated

at <140 °C.

However the value of the ADJ-bypass capacitor

should be chosen with respect to the following

equation:

Taking the FR-4 printed circuit board and 1/16

thick with 1 ounce copper foil as an experiment

(fig.13), the PCB material is effective at trans-

mitting heat with the tab attached to the pad area

and a ground plane layer on the backside of the

substrate. Refer to table 1 for the results of the

experiment.

C = 1 / ( 6.28 * F_R* R₁)

Where

C = value of the capacitor in Farads

(select an equal or larger standard value),

F_R= ripple frequency in Hz,

R₁= value of resistor R1 in Ohms.

The thermal interaction from other components

in the application can effect the thermal resis-

tance of the SPX1117. The actual thermal

resistance can be determined with experimenta-

tion.

If an ADJ-bypass capacitor is used, the ampli-

tude of the output ripple will be independent of

the output voltage. If an ADJ-bypass capacitor

isnotused, theoutputripplewillbeproportional

to the ratio of the output voltage to the reference

voltage:

SPX1117 power dissipation is calculated as

follows:

M = V_OUT/ V_REF

P_D= (V_IN- V_OUT)(I_OUT

)

Where M = multiplier for the ripple seen when

the ADJ pin is optimally bypassed.

Maximum Junction Temperature range:

T_J= T_A(max) + P_D* thermal resistance

(junction-to-ambient)

V_REF=1.25V

Maximum junction temperature must not ex-

ceed the 125°C.

Ripple rejection for the adjustable version is

shown in Figure 20.

Output Voltage

V_OUT= V_REF(1+ (R₂/R₁)) + I_ADJ* R₂,

The output of the adjustable regulator can be set

to any voltage between 1.25V and 15V. The

valueofV_OUTcanbequicklyapproximatedusing

the formula

where

V_REF=1.25V.

V_OUT=1.25 *(R₁+ R₂)/R₁.

Layout Considerations

Parasitic line resistance can degrade load regu-

lation. Inordertoavoidthis, connect R directly

to V_OUTas illustrated in Figure 25. For¹the same

reason, R₂should be connected to the negative

side of the load.

A small correction to this formula is required

depending on the values of resistors R and R₂,

since the adjustable pin current (appro¹x 50µA)

flows through R₂. When I_ADJis taken into ac-

count, the formula becomes
