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.

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.
FIGURE 1
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.
