DESCRIPTION:

The MSK109RH is a 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 MSK109RH is a hermetically sealed surface mount ceramic package with optional straight

or gull wing lead form.

NOTES:

Unless otherwise speciﬁed; IR=1mA, ADJ=OPEN.

Guaranteed by design but not tested. Typical parameters are representative of actual device performance but are for reference only. Not

applicable to post irradiation performance.

Industrial and Prototype grade devices shall be tested to subgroup 1 unless otherwise speciﬁed.

Military grade and EDU devices shall be 100% tested to subgroups 1,2 and 3.

Subgroup 1 TA = TC = +25°C

Subgroup 2 TA = TC = +125°C

Subgroup 3 TA = TC = -55°C

Continuous operation at or above absolute maximum ratings may adversely eﬀect the device performance and/or life cycle.

Pre and Post irradiation limits at 25°C, to 100Krads TID, are identical unless otherwise speciﬁed. Post irradiation performance is guaranteed by

design with a 2X radiation design margin.

APPLICATION NOTES

BREAKDOWN VOLTAGE

Figure 3 shows the MSK109RH conﬁgured with the MSK5977RH 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 resistor 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.

The breakdown voltage of the MSK109RH 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 reference. The output voltage trim range

for the circuit is approximately ±5%. Leave the adjust pin unconnected if

the adjust feature is not used.

PRECISION REFERENCE FOR LINEAR REGULATOR

The MSK109RH provides increased initial accuracy and reduced

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

MSK5976RH, MSK5977RH and the MSK5953RH radiation hardened linear

regulators. The MSK5977RH is used in the provided examples. Refer to

the respective data sheets for more speciﬁc information on each device.

Figure 2 shows the MSK109RH conﬁgured to set a precision current in a

resistor divider network setting the ﬁnal output voltage of the MSK5977RH.

This conﬁguration allows the output voltage of the MSK5977 to be adjusted

between 0V and the maximum range of the MSK5977RH. 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 MSK109RH reference. To

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

low and/or matching TCR. This conﬁguration swamps out initial accuracy

error, temperature drift, drift due to irradiation, line regulation and load

regulation error of the set pin current. The MSK109RH may be biased from

Vin,nVcontrol or a separate source but it must be greater than Vout by 2.5Vh

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

output load must sink the minimum load current from the MSK5977RH

plus the current passing through the MSK109RH to maintain regulation.

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

TOTAL DOSE RADIATION TEST PERFORMANCE

Radiation performance curves for TID testing have been generated

for all radiation testing performed by MS Kennedy. These curves show

performance trends throughout the TID test process and are located in

the MSK109RH radiation test report. The complete radiation test report

is available in the RAD HARD PRODUCTS section on the MSK website.
