Typical parameters are representative of actual device performance but are for reference only. 3 All output parameters are tested using a low duty cycle pulse to maintain TJ = TC. 4 Industrial grade and "E" suffix devices shall be tested to subgroup 1 unless otherwise specified. 5 Military grade devices ("H" suffix) shall be 100% tested to subgroups 1,2 and 3. 6 Subgroup 1 TA=TC=+25°C 2 TA=TC=+125°C 3 TA=TC=-55°C 7 Please consult the factory if alternate output voltages are required. 8 Input voltage (VIN= VOUT + a specified voltage) is implied to be more negative than VOUT. 9 Continuous operation at or above absolute maximum ratings may adversely effect the device performance and/or life cycle MSK5330-15 2 Rev. B 10/05 APPLICATION NOTES BYPASS CAPACITORS For most applications a 33uF minimum, low ESR (0.5-2 ohm) tantalum capacitor should be attached as close to the regulator's output as possible. This will effectively lower the regulator's output impedance, increase transient response and eliminate any oscillations that are normally associated with low dropout regulators. Additional bypass capacitors can be used at the remote load locations to further improve regulation. These can be either of the tantalum or the electrolytic variety. Unless the regulator is located very close to the power supply filter capacitor(s), a 4.7uF minimum low ESR (0.5-2 ohm) tantalum capacitor should also be added to the regulator's input. An electrolytic may also be substituted if desired. When substituting electrolytic in place of tantalum capacitors, a good rule of thumb to follow is to increase the size of the electrolytic by a factor of 10 over the tantalum value. OVERLOAD SHUTDOWN The MSK 5330 features both power and thermal overload protection. When the maximum power dissipation is not exceeded, the regulator will current limit slightly above its 3 amp rating. As the Vin-Vout voltage increases, however, shutdown occurs in relation to the maximum power dissipation curve. If the device heats enough to exceed its rated die junction temperature due to excessive ambient temperature, improper heat sinking etc., the regulator will shutdown until an appropriate junction temperature is maintained. It should also be noted that in the case of an extreme overload, such as a sustained direct short, the device may not be able to recover. In these instances, the device must be.
