DESCRIPTION:

The MSK 110RH is a dual 2.5V radiation hardened shunt regulator diode with an excellent initial voltage tolerance of

±5mV and very good stability over temperature. This voltage reference features a wide current range and a low dynamic

impedance that is maintained over the full temperature range. The adjustment terminal allows the reference voltage to be

adjusted to compensate for system errors. The MSK 110RH is a hermetically sealed surface mount ceramic package with

optional straight or gull wing lead form.

APPLICATION NOTES

BREAKDOWN VOLTAGE

The breakdown voltage of the MSK 110RH can be optimized to

meet the applications circuit requirement and/or adjust for the initial

voltage tolerance. As shown in Figure 1, a 10K potentiometer is

added in parallel with the V+ and V- of the voltage reference with

the potentiometer adjust pin connected to ADJ of the voltage refer-

ence. The output voltage trim range for the circuit is approximately

±5%. Leave the adjust pin unconnected if the adjust feature is not

used.

Figure 3 shows the MSK 110RH configured with the MSK 5977RH

to provide the same accuracy improvement benefits as the circuit

above but require less voltage overhead and it does not require the

load to sink the divider current. This configuration is limited to an

output operating range of 0V to 2.5V. For 2.5V output R1 would be

zero ohms leaving the set pin of the regulator connected directly to

the V+ terminal of the reference; R2 can also be omitted (left open)

in the 2.5V configuration. Select Rs or a current source to maintain

between one and ten milliamps in the reference and supply the re-

sistor divider current under all operating conditions. The resistor

divider current should be 1mA or greater to swamp out the effects

of the set pin current except in the 2.5V (no divider) case. As above,

R1 and R2 tolerance should be 0.1% or better tolerance with low

and/or matching TCR for best accuracy.

PRECISION REFERENCE FOR LINEAR REGULA-

TOR

The MSK 110RH provides increased initial accuracy and reduced

drift due to temperature and irradiation to the output accuracy of the

MSK 5976RH, MSK 5977RH and the MSK 5953RH radiation hard-

ened linear regulators. The MSK 5977RH is used in the provided

examples. Refer to the respective data sheets for more specific

information on each device. Figure 2 shows the MSK 110RH con-

figured to set a precision current in a resistor divider network set-

ting the final output voltage of the MSK 5977RH. This configuration

allows the output voltage of the MSK 5977 to be adjusted between

0V and the maximum range of the MSK 5977RH. The current in R1

is equal to the reference voltage divided by R1. The current in R2 is

equal to the current in R1 plus the 10uA nominal set pin current. By

setting the current in R1 to 1mA or greater the accuracy error of the

set pin current is swamped out by the higher accuracy of the MSK

110RH reference. To maintain high accuracy R1 and R2 tolerance

should be 0.1% or better with low and/or matching TCR. This con-

figuration swamps out initial accuracy error, temperature drift, drift

due to irradiation, line regulation and load regulation error of the set

pin current. The MSK 110RH may be biased from Vin, Vcontrol or a

separate source but it must be greater than Vout by 2.5V plus the

drop across RS; VMIN=VOUT+2.5VREF+VRS. The minimum output

load must sink the minimum load current from the MSK 5977RH

plus the current passing through the MSK 110RH to maintain regu-

lation. The source used to bias the reference must also supply the

divider current set by the reference and the R1.

To maintain high accuracy R1 and R2 tolerance should be 0.1% or

better with low and/or matching TCR
