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

E 10/12 APPLICATION NOTES CAPACITOR SELECTION HEAT SINKING INPUT CAPACITOR: Input bypass capacitors are 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 for each input will be suitable. 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 OUTPUT CAPACITOR: A minimum of a 1μF solid tantalum capacitor should also be used at both outputs to insure stability. Any increase of this output capacitor larger than 10μF will only improve output impedance. +CCOMP CAPACITOR; POSITIVE REGULATOR: 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. EXAMPLE: 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 1.) Assume 45° heat spreading model. 2.) Find positive regulator power dissipation: -CCOMP CAPACITOR; NEGATIVE REGULATOR: 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. 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 = 11.5°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 - 11.5°C/W - 0.15°C/W = 11.7°C/W The same exercise must be performed for the negative regulator. TYPICAL APPLICATION CIRCUIT 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 can be located in the MSK 5911RH radiation test report. The complete radiation test report is available in the RAD HARD PRODUCTS section on the MSK website. LOAD REGULATION http://www.mskennedy.com/store.asp?pid=9951&catid=19680 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.
