Pin Functions

PIN I/O DESCRIPTION
NAME NO.
EN 3 I Enable pin. Drive this pin over 1.2 V to turn on the regulator. Drive this pin below 0.4 V to put the regulator into shutdown mode, reducing operating current to 18 nA, typical.
GND 2, 4 — Ground pin. Tie all ground pins to ground for proper operation.
IN 1 I Input pin. For stable operation, place a small, 0.1-μF capacitor from this pin to ground; typical input capacitor = 1.0 μF. Tie back both input and output capacitor grounds to the IC ground, with no significant impedance between them.
OUT 5 O Regulated output voltage pin. Connect a small (1-μF or greater) ceramic capacitor from this pin to ground for stable operation. See the Input and Output Capacitor Requirements in the Application and Implementation section for more details.
