LT1765-5, Lower the Output Voltage Ripple of Positive-to-Negative DC/DC Converters with Optimum Capacitor Hook-Up
Circuit shows LT1765 5V to 5V converter with the bulk cap between VIN and ground has much higher output ripple than the circuit in Figure 1a. The high dI/dt path, indicated here with bold red lines, includes the output capacitor, thus increasing output ripple
