MAX6138BEXR30 - Maxim Integrated Products, Inc.

General Description

The MAX6138 is a precision, two-terminal shunt mode,

bandgap voltage reference available in fixed reverse

breakdown voltages of 1.2205V, 2.048V, 2.5V, 3.0V,

4.096V, and 5.0V. Ideal for space-critical applications,

the MAX6138 is offered in the subminiature 3-pin SC70

surface-mount package (1.8mm X 1.8mm), 50% smaller

than comparable devices in SOT23 surface-mount

packages.

Laser-trimmed resistors ensure precise initial accuracy.

With a 25ppm/°C temperature coefficient, the device is

offered in three grades of initial accuracy ranging from

0.1% to 0.5%. The MAX6138 has a 60µA to 15mA shunt-

current capability with low-dynamic impedance, ensuring

stable reverse breakdown voltage accuracy over a wide

range of operating temperatures and currents.

The MAX6138 does not require an external stabilizing

capacitor while ensuring stability with capacitive loads.

The MAX6138 is a higher precision device in a smaller

package than the LM4040/LM4050.

Detailed Description

The MAX6138 shunt reference uses the bandgap prin-

ciple to produce a stable, accurate voltage. The device

behaves similarly to an ideal zener diode; a fixed volt-

age is maintained across its output terminals when

biased with 60µA to 15mA of reverse current. The

MAX6138 behaves similarly to a silicon diode when

biased with forward currents up to 10mA.

Figure 3 shows a typical operating circuit. The

MAX6138 is ideal for providing a stable reference from

a high-voltage power supply.

Applications Information

The MAX6138’s internal pass transistor is used to main-

tain a constant output voltage (VSHUNT) by sinking the

necessary amount of current across a source resistor.

The source resistance (RS) is determined from the load

current (ILOAD) range, supply voltage (VS) variations,

VSHUNT, and desired quiescent current.

Choose the value of RSwhen VSis at a minimum and

ILOAD is at a maximum. Maintain a minimum ISHUNT of

60µA at all times. The RSvalue should be large enough

to keep ISHUNT less than 15mA for proper regulation

when VSis maximum and ILOAD is at a minimum. To

prevent damage to the device, ISHUNT should never

exceed 20mA.

Therefore, the value of RSis bounded by the following

equation:

[VS(MIN) - VR] / [60µA + ILOAD(MAX)] > RS>

[VS(MAX) - VR] / [20mA + ILOAD(MIN)]

Choosing a larger resistance minimizes the total power

dissipation in the circuit by reducing the shunt current

(PD(TOTAL) = VSX ISHUNT). Provide a safety margin to

incorporate the worst-case tolerance of the resistor

used. Ensure that the resistor’s power rating is ade-

quate, using the following general power equation:

PDR= ISHUNT ✕(VS(MAX) - VSHUNT)

Output Capacitance

The MAX6138 does not require an external capacitor

for operational stability and is stable for any output

capacitance.

Temperature Performance

The MAX6138 typically exhibits an output voltage tem-

perature coefficient within ±4ppm/°C. The polarity of

the temperature coefficient may be different from one

device to another; some may have positive coefficients,

and others may have negative coefficients.
