NOTES FOR APPLICATION CIRCUIT:
(1) C
IN is needed if the device is far from the supply’s filter capacitors, or for operation from a battery. A value of
1.0F or greater should be used. C
IN may be a tantalum or aluminum electrolytic capacitor.
(2) C
O should be a 1F or greater tantalum or aluminum electrolytic capacitor. Larger value capacitors will improve
the overall transient response. Due to their very low ESR, ceramic capacitors should not be used.
(3) C
BYP (required) should be placed as close as possible to pin 4 and ground. A 10nF ceramic capacitor is recom-
mended.
(4) EN should be tied to VIN if the shutdown feature is not required. Maximum EN voltage = VIN.
