NAME DDC DESCRIPTION
Regulated output voltage pin. A small (1mF) ceramic capacitor is needed from this pin to ground to
OUT 5 assure stability. See the Input and Output Capacitor Requirements in the Application Information
section for more details.
N/C — Not connected.
Driving the enable pin (EN) over 1.2V turns ON the regulator. Driving this pin below 0.4V puts the
EN 3
regulator into shutdown mode, reducing operating current to 18nA typical.
GND 2, 4 ALL ground pins must be tied to ground for proper operation.
Input pin. A small capacitor is needed from this pin to ground to assure stability. Typical input capacitor
IN 1 = 1.0mF. Both input and output capacitor grounds should be tied back to the IC ground with no
significant impedance between them.
Thermal pad — It is recommended that the thermal pad on the SON-6 package be connected to ground.
