Layout Consideration

It is recommended that output capacitors be located as close as possible to the VOUT terminal of the

device to prevent any high frequency oscillation that may result due to excessive stray inductance.

Specfications for capacitors: 330µF Tantalum Low ESR, 220µF Electrolytic, 22µF Electrolytic
