Pin Functions

PIN I/O DESCRIPTION
NAME SON SOT
OUT 1 5 O Regulated output voltage pin. A small (1-μF) ceramic capacitor is needed from this pin to ground to assure stability. See Input and Output Capacitor Requirements for more details.
N/C 2 — — Not connected.
VSET/FB 3 4 I Feedback pin (FB) for adjustable versions; VSET for fixed voltage versions. Drive the select pin (VSET) below 0.4 V to select preset output voltage high. Drive the VSET pin over 1.2 V to select preset output voltage low.
EN 4 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 5 2 — Ground pin. Tie all ground pins to ground for proper operation.
IN 6 1 I Input pin. A small capacitor is needed from this pin to ground to assure stability. A typical input capacitor is 1.0 μF. Tie back both input and output capacitor ground to the IC ground, with no significant impedance between them.
Thermal pad — — — (SON package only) Connect the thermal pad to ground.
