9 Power Supply Recommendation
9.1 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.
