. _ Stabilizes Power Supply Feedback Loop «Reduces Power Supply Signal Gain 2 . Effective For Signals:100<Hz to 100MHz ¥ «Effective Impedance for Power Supply Noise Signal:<1 Ohm . Low Energy Storage(Important For Safety Applications) GND «Eliminates The Need For Series Ferrite Beads For Power Supply Er Filtering(Application Dependent) T P103 Power Supply Damping Circuit(PSDC) suppresses high frequency noise on the DC power supply lines as well as reducing EMI rediated from the applications themselves. To achieve this the P103 provides a low impedance path from Vee to GND for signals above 100KHz. This device is designed to stabilize power supply resonance circuits in applications such as: © Logic circuits * Radio/TV frequency systems «High performance ADC and DAC ‘+ Mixed signal applications By connecting the Vszr input trough a series resistor to Vee the PSDC impedance can be lowered further(Note:By exceeding the ‘maximal allowable current consumption of 30mA the device may be damaged). When the Vrer input is connected to GND the PSDC will become inactive which is useful in high frequency test applications. ‘The PSDC functions as an AC coupled shunt regulator and can be paralleled to improve the performance of a system.
