Reference
Input; Bypass directly at the IC with a 1 mF ceramic capacitor to Ground
Enable for output regulator 1; raise above 0.95 V to enable V
Enable for output regulator 2; raise above 0.95 V to enable V
NC; Do not make connection to these pins
Ground
The thermal pad should be connected to ground for best thermal performance. Float if necessary
Output 2; Bypass to GND with a capacitor, 4.7 mF ≥ C ≥ 0.7 mF, any ESR
Output 1; Bypass to GND with a capacitor, 4.7 mF ≥ C ≥ 0.7 mF, any ESR
