This provides a DC load of 375mA when the regulated output voltage is 3.3V. A standard 2A bench supply was used to provide power to the application circuit. The transient response waveforms shown in the Typical Performance Characteristics section were obtained by switching a 6.3Ω resistor across the out- put. Temperature Performance The graph below shows thermal performance for the CS5231-3 across the normal operating output current range. Figure 7: Package Temperature vs Load Current (VIN = 5V, TA =23 C°) PFET RDS(ON) Performance The graph provided below show typical RDS(ON) perfor- mance for the PFET. The data is provided as VDS vs IOUT for different values of VAUX.
