10 Power Supply Recommendations

10.1 Power Supply Decoupling

Both the REGIN input pin and the VCC output pin require low equivalent series resistance (ESR) ceramic capacitors placed as closely as possible to the respective pins to optimize ripple rejection and provide a stable and dependable power rail that is resilient to line transients. A 0.1-µF capacitor at the REGIN and a 1-µF capacitor at VCC will suffice for satisfactory device performance.
