FEATURES

DESCRIPTIO

The LT^®1460S3 is a family of SOT-23 micropower series

references that combine high accuracy and low drift with low

power dissipation and small package size. These series

references use curvature compensation to obtain low tem-

perature coefficient, and laser trimmed precision thin-film

resistors to achieve high output accuracy. Furthermore,

output shift due to PC board soldering stress has been

dramatically reduced. These references will supply up to

20mA, making them ideal for precision regulator applica-

tions, yet they are almost totally immune to input voltage

variations.

Note 1: Absolute Maximum Ratings are those values beyond which the life

of a device may be impaired.

Note 2: The LT1460S3 is guaranteed functional over the operating

temperature range of –40°C to 85°C.

Note 4: ESD (Electrostatic Discharge) sensitive devices. Extensive use of

ESD protection devices are used internal to the LT1460S3, however, high

electrostatic discharge can damage or degrade the device. Use proper ESD

handling precautions.

Note 5: Temperature coefficient is measured by dividing the change in

output voltage by the specified temperature range. Incremental slope is

also measured at 25°C.

Note 3: If the parts are stored outside of the specified temperature range,

the output may shift due to hysteresis.

ELECTRICAL CHARACTERISTICS

Note 6: Load regulation is measured on a pulse basis from no load to the

specified load current. Output changes due to die temperature change

must be taken into account separately.

Note 7: Thermal regulation is caused by die temperature gradients created

by load current or input voltage changes. This effect must be added to

normal line or load regulation. This parameter is not 100% tested.

Note 10: Long-term stability typically has a logarithmic characteristic and

therefore, changes after 1000 hours tend to be much smaller than before

that time. Total drift in the second thousand hours is normally less than

one third that of the first thousand hours with a continuing trend toward

reduced drift with time. Long-term stability will also be affected by

differential stresses between the IC and the board material created during

board assembly.

Note 8: Excludes load regulation errors.

Note 11: Hysteresis in output voltage is created by package stress that

differs depending on whether the IC was previously at a higher or lower

temperature. Output voltage is always measured at 25°C, but the IC is

cycled to 70°C or 0°C before successive measurements. Hysteresis is

roughly proportional to the square of the temperature change. Hysteresis

is not normally a problem for operational temperature excursions where

the instrument might be stored at high or low temperature. See

Applications Information.

Note 9: Peak-to-peak noise is measured with a single pole highpass filter

at 0.1Hz and 2-pole lowpass filter at 10Hz. The unit is enclosed in a still-air

environment to eliminate thermocouple effects on the leads. The test time

is 10 sec. RMS noise is measured with a single pole highpass filter at

10Hz and a 2-pole lowpass filter at 1kHz. The resulting output is full wave

rectified and then integrated for a fixed period, making the final reading an

average as opposed to RMS. A correction factor of 1.1 is used to convert

from average to RMS and a second correction of 0.88 is used to correct

for the nonideal bandpass of the filters.

APPLICATIONS INFORMATION

capacitive load, these references are ideal for fast settling

or applications where PC board space is a premium. The

test circuit shown in Figure 1 is used to measure the

response time and stability of various load currents and

load capacitors. This circuit is set for the 2.5V option. For

other voltage options, the input voltage must be scaled up

and the output voltage generator offset voltage must be

adjusted. The 1V step from 2.5V to 1.5V produces a

current step of 10mA or 1mA for R_L= 100Ω or R_L= 1k.

Figure2showstheresponseofthereferencetothese1mA

and 10mA load steps with no load capacitance, and Figure

3 shows a 1mA and 10mA load step with a 0.1µF output

capacitor. Figure 4 shows the response to a 1mA load step

with C_L= 1µF and 4.7µF.

Longer Battery Life

Series references have a large advantage over older shunt

style references. Shunt references require a resistor from

the power supply to operate. This resistor must be chosen

to supply the maximum current that can ever be

demanded by the circuit being regulated. When the circuit

beingcontrolledisnotoperatingatthismaximumcurrent,

the shunt reference must always sink this current, result-

ing in high dissipation and short battery life.

The LT1460S3 series references do not require a current

setting resistor and can operate with any supply voltage

from V_OUT+ 0.9V to 20V. When the circuitry being regu-

lated does not demand current, the LT1460S3s reduce

their dissipation and battery life is extended. If the refer-

ences are not delivering load current, they dissipate only

several mW, yet the same connection can deliver 20mA of

load current when demanded.

Long-Term Drift

Long-term drift cannot be extrapolated from acceler-

ated high temperature testing. This erroneous tech-

niquegivesdriftnumbersthatarewidelyoptimistic.The

only way long-term drift can be determined is to mea-

sure it over the time interval of interest. The LT1460S3

long-term drift data was taken on over 100 parts that were

soldered into PC boards similar to a “real world” applica-

tion.Theboardswerethenplacedintoaconstanttempera-

ture oven with T_A= 30°C, their outputs were scanned

regularly and measured with an 8.5 digit DVM. Figure 5

APPLICATIONS INFORMATION

Hysteresis

Fast Turn-On

HysteresisdatashowninFigure5andFigure6represents

the worst-case data taken on parts from 0°C to 70°C and

from –40°C to 85°C. The output is capable of dissipating

relatively high power, i.e., for the LT1460S3-2.5, P_D=

17.5V • 20mA = 350mW. The thermal resistance of the

SOT-23 package is 325°C/W and this dissipation causes

a 114°C internal rise producing a junction temperature of

T_J=25°C+114°C=139°C.Thiselevatedtemperaturewill

cause the output to shift due to thermal hysteresis. For

highest performance in precision applications, do not

let the LT1460S3’s junction temperature exceed 85°C.

It is recommended to add a 0.1µF or larger bypass

capacitor to the input pin of the LT1460S3s. Although this

can help stability with large load currents, another reason

is for proper start-up. The LT1460S3 can start in 10µs, but

it is important to limit the dv/dt of the input. Under light

load conditions and with a very fast input, internal nodes

overslew and this requires finite recovery time. Figure 8

showstheresultofnobypasscapacitanceontheinputand

no output load on the LT1460S3-5. In this case the supply

dv/dt is 7.5V in 30ns which causes internal overslew, and

the output does not bias to 5V until 40µs after turn-on.

Although 40µs is a typical turn-on time, it can be much

longer. Figure 9 shows the effect of a 0.1µF bypass

capacitor which limits the input dv/dt to approximately

7.5V in 20µs. The part always starts quickly.

APPLICATIONS INFORMATION

Output Accuracy

Total worst-case output error is:

0.2% + 0.04% + 0.14% = 0.380%

Like all references, either series or shunt, the error budget

of the LT1460S3s is made up of primarily three compo-

nents: initial accuracy, temperature coefficient and load

regulation.Lineregulationisneglectedbecauseittypically

contributes only 150ppm/V. The LT1460S3s typically

shift 0.02% when soldered into a PCB, so this is also

neglected. The output errors are calculated as follows for

a 100µA load and 0°C to 70°C temperature range:

Table 2 gives the worst-case accuracy for LT1460HCS3,

LT1460JCS3 and LT1460KCS3 from 0°C to 70°C, and

shows that if the LT1460HCS3 is used as a reference

instead of a regulator, it is capable of 8 bits of absolute

accuracy over temperature without a system calibration.
