(for SO-8)

The SPX2945 is a low power voltage regulator. This device is an excellent choice for use in battery-powered

applications such as cordless telephones, radio control systems, and portable computers. The SPX2945

features very low quiescent current (100µA Typ.) and very low dropout voltage. This includes a tight initial

tolerance of 1% max and very low output temperature coefficient, making the SPX2945 useful as a low-

power voltage reference.

The error flag output feature is used as power-on reset for warning of a low output voltage, due to a falling

voltage input of batteries. Another feature is the logic-compatible shutdown input which enables the

regulator to be switched on and off. The SPX2945 is offered in 3-pin TO-220 package, SO-8 (same pin

out as SPX2951), SOT-223, surface mount 3-Pin TO-252, 3-Pin TO-263 packages and 5-Pin TO-263.

The regulator output voltage (of the 8-pin SO-8) may be pin-strapped for a 3.3V and 5.0V or programmed

from 1.24V to 20V with an external pair of resistors. Look for SPX2951 for 150mA and SPX2954 for 250mA

applications.

ELECTRICAL CHARACTERISTICS: Continued

Electrical characteristics at VIN = VO+1V, IO = 1mA, COUT = 2.2µF, TA = 25°C, unless otherwise specified. ♦ applies over the

full operating temperature range.

Note 1: Output or reference voltage temperature coefficients defined as the worst case voltage change divided by

the total temperature range.

Note 2: Unless otherwise specified all limits are guaranteed for Tj = 25°C, VIN = 6V, IL = 1mA and CL = 2.2µF. Additional

conditions for the 8-pin versions are feedback tied to 5V/3.3V tap and output tied to output sense (VOUT = 5V) and

VSHUTDOWN ≤ 0.8V.

Note 3: Regulation is measured at constant junction temperature, using pulse testing with a low duty cycle. Changes

in output voltage due to heating effects are covered under the specification for thermal regulation.

Note 4: Line regulation for the SPX2945 is tested at 150°C for IL = 1 mA. For TJ = 125°C, line regulation is guaranteed

by design.

Note 5: Dropout voltage is defined as the input to output differential at which the output voltage drops 100 mV below

its nominal value measured at 1V differential at very low values of programmed output voltage, the minimum input

supply voltage of 2V ( 2.3V over temperature) must be taken into account.

Note 6: Comparator thresholds are expressed in terms of a voltage differential at the feedback terminal below the

nominal reference voltage measured at 6V input. To express these thresholds in terms of output voltage change,

multiply by the error amplifier gain = VOUT/VREF = (R1 + R2)/R2. For example, at a programmed output voltage of 5V,

the Error output is guaranteed to go low when the output drops by 95 mV x 5V/1.235 = 384 mV. Thresholds remain

constant as a percent of VOUT as VOUT is varied, with the dropout warning occurring at typically 5% below nominal, 7.5%

guaranteed.

Note 7: VSHUTDOWN ≥ 2V, VIN ≤ 26V, VOUT = 0, Feedback pin tied to 5V/3.3V Tap.

External Capacitors

The stability of the SPX2945 requires a 2.2µF or

greater capacitor between output and ground.

Oscillation could occur without this capacitor.

Most types of tantalum or aluminum electrolytic

works fine here. For operations of below -25°C

solid tantalum is recommended since the many

aluminum types have electrolytes that freeze at

about -30°C. The ESR of about 5Ω or less and

resonant frequency above 500kHz are the most

important parameters in the value of the capaci-

tor. The capacitor value can be increased with-

out limit.

At lower values of output current, less output

capacitance is required for stability. For the

currents below 10mA the value of the capacitor

can be reduced to 0.5µF and 0.15µF for 1mA.

More output capacitance needed for the 8-pin

version at voltages below 5V since it runs the

error amplifier at lower gain. At worst case

4.7µF or greater must be used for the condition

of 250mA load at 1.23V output.

The SPX2945, unlike other low dropout regu-

lators will remain stable and in regulation with

no load in addition to the internal voltage di-

vider. This feature is especially important in

applications like CMOS RAM keep-alive.

If there is more than 10 inches of wire between

the input and the AC filter capacitor, or if a

battery is used as the input, then a 0.1µF tanta-

lum or aluminum electrolytic capacitor should

be placed from the input to the ground.

Instability can occur if there is stray capaci-

tance to the SPX2945 feedback terminal (pin 7).

This could cause more problems when using a

higher value of external resistors to set the

output voltage.

This problem can be fixed by adding a 100pF

capacitor between output and feedback and

increasing the output capacitor to at least 3.3µF.

Error Detection Comparator Output

The Comparator produces a logic low output

whenever the SPX2945 output falls out of regu-

lation by more than around 5%. This is around

60mV offset divided by the 1.235 reference

voltage. This trip level remains 5% below

normal regardless of the programmed output

voltage of the regulator. Figure 1 shows the

timing diagram depicting the ERROR signal

and the regulator output voltage as the SPX2945

input is ramped up and down. The ERROR

signal becomes low at around 1.3V input, and

goes high around 5V input (input voltage at

which VOUT = 4.75). Since the SPX2945’s

dropout voltage is load dependent, the input

voltage trip point (around 5V) will vary with the

load current. The output voltage trip point

(approx. 4.75V) does not vary with load.

The error comparator has an open-collector out-

put, which requires an external pull-up resistor.

Depending on the system requirements the re-

sistor may be returned to 5V output or other

supply voltage. In determining the value of this

resistor, note that the output is rated to sink

400µA; this value adds to battery drain in a low

battery condition. Suggested values range from

100K to 1MΩ. If the output is unused this

resistor is not required.

Programming the Output Voltage of

SPX2945

The SPX2945 may be pin-strapped for 5V or

3.3V using its internal voltage divider by tying

Pin 1 (output) to Pin 2 (sense) and Pin 7 (feed-

back) to Pin 6 (5V/3.3V Tap).

Also, it may be programmed for any output

voltage between its 1.235V reference and its

20V maximum rating. As seen in Figure 2, an

external pair of resistors is required.

Refer to the below equation for the program-

ming of the output voltage::

VOUT = VREF x ( 1 + R1/ R2 )+ IFBR1

The VREF is 1.235 and IFB is the feedback bias

current, nominally -20nA. The minimum rec-

ommended load current of 1 µA forces an upper

limit of 1.2 MΩ on value of R2. If no load is

presented the IFB produces an error of typically

2% in VOUT, which may be eliminated at room

temperature by trimming R1. To improve the

accuracy choose the value of R2 = 100k; this

reduces the error by 0.17% and increases the

resistor program current by 12µA. Since the

SPX2945 typically draws 60 µA at no load with

Pin 2 open-circuited this is a small price to pay.

Reducing Output Noise

It may be an advantage to reduce the AC noise

present at the output. One way is to reduce the

regulator bandwidth by increasing the size of

the output capacitor. This is the only way that

noise can be reduced on the 3 lead SPX2945 but

is relatively inefficient, as increasing the ca-

pacitor from 1µF to 220µF only decreases the

noise from 430µV to 160µV Vrms for a 100kHz

bandwidth at 5V output. Noise could also be

reduced fourfold by a bypass capacitor across

R1, since it reduces the high frequency gain from

4 to unity. Pick

CBYPASS ≅1 / 2πR1 x 200 Hz

or choose 0.01µF. When doing this, the output

capacitor must be increased to 3.3µF to main-

tain stability. These changes reduce the output

noise from 430µV to 100µV Vrms for a 100kHz

bandwidth at 5V output. With the bypass ca-

pacitor added, noise no longer scales with out-

put voltage so that improvements are more dra-

matic at higher output voltages.
