11.1 Layout Guidelines

Traces on the input and output pins should be thick enough to carry 1.5 A of current without violating thermal requirements of the device or the system. In addition, a 1-µF solid tantalum capacitor is required on the input pin if the regulator is more than 10 cm from the power supply filter capacitor. A 1-µF solid tantalum or 10-µF aluminum electrolytic capacitor is required on the output pin for stability.
