APPLICATION CIRCUIT OF FIXED/FIXED VERSION
APPLICATION CIRCUIT OF FIXED/ADJ VERSION
NOTE: The regulator is designed to be stable with either tantalum or ceramic capacitors on the input and outputs. The expected values of
the input and output X7R ceramic capacitors are from 4.7µF to 22µF with 4.7µF typical. The input capacitor must be connected within 0.5
inches of the V
to the size of the input capacitor (for more details see the Application Hints section).
