For this operating condition, TJ is lower than the absolute maximum operating junction temperature, 125°C,
so it is safe to use the A6318 in this configuration.
Layout considerations
To improve ac performance such as PSRR, output noise, and transient response, it is recommended that the
PCB be designed with separate ground planes for VIN and VOUT, with each ground plane connected only at the
GND pin of the device. In addition, the ground connection for the bypass capacitor should connect directly to
the GND pin of the device.
