10 Power Supply Recommendation

10.1 Power Supply Decoupling

Both the VPWR input pin and the REG25 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 VPWR and a 1-µF

capacitor at REG25 will suffice for satisfactory device performance.
