Guaranteed by design but not tested. Typical parameters are representative of actual device
performance but are for reference only.
Industrial grade and "E" suffix devices shall be tested to subgroup 1 unless otherwise specified.
Military grade 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
Please consult the factory if alternate output voltages are required.
For positive regulator, output decoupled to ground using 1µF minimum tantalum capacitor unless
otherwise specified. For negative regulator, output decoupled to ground using 1µF minimum
tantanlum capacitor.
Consult factory for post radiation limits.
Continuous operation at or above absolute maximum ratings may adversly effect the device
performance and/or life cycle.

APPLICATION NOTES
TYPICAL APPLICATION CIRCUIT
CAPACITOR SELECTION
POSITIVE REGULATOR
INPUT CAPACITOR:
An input bypass capacitor is recommenced when using the
MSK 5911 series regulators. This is especially true if the regulator is located farther than 6 inches from the power supply filter
capacitors. For most applications a 1µF solid tantalum capacitor
will be suitable.
OUTPUT CAPACITOR:
A minimum of a 1µF solid tantalum capacitor should also be
used at the output to insure stability. Any increase of this output capacitor larger than 10µF will only improve output impedance.
LOAD REGULATION
It is important to keep the output connection between the regulator and the load as short as possible since this directly affects
the load regulation. For example, if 20 gauge wire were used
which has a resistance of about 0.008 ohms per foot, this would
result in a drop of 8mV/ft at 1Amp of load current. It is also
important to follow the capacitor selection guidelines to achieve
best performance.
+CCOMP CAPACITOR:
For improved ripple rejection, +Ccomp can be bypassed to
ground with a 10µF tantalum capacitor. This bypass capacitor
will provide 80dB ripple rejection. Increased capacitance above
10µF does not improve the ripple rejection at frequencies above
120Hz. If the Ccomp bypass capacitor is used, it may be necessary to add a protection diode to protect the regulator from capacitor discharge damage. See Typical Applications Circuit for
clarification. If the bypass capacitor is not used, it should be left
open since it is internally connected to the regulator.
HEAT SINKING
To determine if a heat sink is required for your application
and if so, what type, refer to the thermal model and governing equation below.
Governing Equation: Tj = Pd x (Rθjc + Rθcs + Rθsa) + Ta
WHERE
Tj = Junction Temperature
Pd = Total Power Dissipation
Rθjc = Junction to Case Thermal Resistance
Rθcs = Case to Heat Sink Thermal Resistance
Rθsa = Heat Sink to Ambient Thermal Resistance
Tc = Case Temperature
Ta = Ambient Temperature
Ts = Heat Sink Temperature
NEGATIVE REGULATOR
INPUT CAPACITOR:
Once again, if the regulator will be farther than 6 inches from
power supply filter capacitors, then an input capacitor will be
required on the negative regulator. It is recommended that a
1µF solid tantalum capacitor be used.
EXAMPLE:
OUTPUT CAPACITOR:
A minimum of a 1µF solid tantalum capacitor should also be
used at the output to insure stability. Any increase of this output capacitor larger than 10µF will only improve output impedance.
This example demonstrates an analysis where the output currents are at 0.5 amp each and both inputs are 8V.
Conditions for MSK 5911RH:
+Vin = +8.0V; Iout = 0.5A Positive Regulator
-CCOMP CAPACITOR:
For improved ripple rejection, -Ccomp can be bypassed to
ground with a 10µF tantalum capacitor. This bypass capacitor
will provide 66dB ripple rejection. Increased capacitance above
10µF does not improve the ripple rejection at frequencies above
120Hz. If the Ccomp bypass capacitor is used, it may be necessary to add a protection diode to protect the regulator from capacitor discharge damage. See Typical Applications Circuit for
clarification. If the bypass capacitor is not used, it should be left
open since it is internally connected to the regulator.
1.) Assume 45° heat spreading model.
2.) Find positive regulator power dissipation:
Pd = (Vin - Vout)(Iout)
Pd = (+8V-5V)(0.5A)
Pd = 1.5W
3.) For conservative design, set Tj = +125°C Max.
4.) For this example, worst case Ta = +90°C.
5.) Rθjc = 10.5°C/W from the Electrical Specification Table.
6.) Rθcs = 0.15°C/W for most thermal greases.
7.) Rearrange governing equation to solve for Rθsa:
Rθsa= ((Tj - Ta)/Pd) - (Rθjc) - (Rθcs)
= (125°C-90°C)/1.5W - 10.5°C/W - 0.15°C/W
= 12.7°C/W
The same exercise must be performed for the negative regulator.
