Figure 1. Typical Application Circuit
It is important to connect the GND pin, the input
bypass-capacitor ground lead, and the output filter
capacitor ground lead to a single point (star ground
configuration) to minimize ground noise and improve
regulation. Also, minimize lead lengths to reduce stray
capacitance, trace resistance, and radiated noise, with
preference given to the feedback circuit, the ground
(2.7V ~ 5V)
