Test Circuit and Layout Guidelines

As in any switching regulator ,layout is important. Rapidly switching switching currents associated with

wiring inductance generate voltage transients which can cause problems. For minimal inductance and

ground loops, the length of the leads indicated by heavy lines should be kept as short as possible. Si-

ngle-point grounding (as indicated)or ground plane construction should be used for best results. When

using the Adjustable version, physically locate the programming resistors near the regulator, to keep the

sensitive feedback wiring short.
