Pin Functions

PIN I/O DESCRIPTION
NAME NO.
EN 7 I For DDR VTT application, connect EN to SLP_S3. For any other applications, use EN as the ON/OFF function. Keep EN voltage equal or lower than VIN voltage at all times.
GND 8 — Ground. Signal ground. Connect to negative pin of the output capacitor.
PGND(1) 4 — Power ground output for the LDO
PGOOD 9 O PGOOD output. Indicates regulation.
REFIN 1 I Reference input
REFOUT 6 O Reference output. Connect to GND through 0.1-μF ceramic capacitor. If there is REFOUT capacitor at DDR side, keep the total capacitance on REFOUT pin below 1 μF. The REFOUT pin can not be open.
VIN 10 I 2.5-V or 3.3-V power supply A ceramic decoupling capacitor with a value between 1-μF and 4.7-μF is required.
VLDOIN 2 I Supply voltage for the LDO.
VO 3 O Power output for the LDO. Minimum 20-μF capacitance is required. No maximum capacitance limit.
VOSNS 5 I Voltage sense output for the LDO. Connect to positive pin of the output capacitor or the load.
(1) Thermal pad connection. See Figure 35 in the Thermal Considerations section for additional information.
