To achieve this the P101 provides a low impedance path from Vcc to GND for signals above 1MHz.The PSDC functions as an AC coupled shunt regulator. ‘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 Varr 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 Vazr input is connected to GND the PSDC will become inactive which is useful in high frequency test applications. Due to the AC coupling of the PSDC this device can be paralleled to improve the performance of a system, [MaxReference InputCurent | de | mA ee 10-1
