NOTES:
1 2 3 4 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. Continuous operation at or above absolute maximum ratings may adversly effect the device performance and/or life cycle.

APPLICATION NOTES CAPACITOR SELECTION
POSITIVE REGULATOR
INPUT CAPACITOR: An input bypass capacitor is recommenced when using the MSK 5211 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.
TYPICAL APPLICATION CIRCUIT
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. Increa.
