Description

PGOOD

Power Good open-drain output. When used it should be pulled up to VIN with a resistor. Typi-

cal resistor value is 100kΩ.

Enable Input Pin. This is a high impedance MOS input with CMOS logic level compatibility.

Logic high enables the device; logic low disables the device. EN must be asserted high after

VIN reaches its minimum operating range. For automatic startup EN must be sequenced with

respect to VIN as shown in application circuit. Do not pull this pin higher than VIN + 0.5V.

PWR

Power Input Pin. Must be closely decoupled to PGND pin with a 4.7μF or greater ceramic

capacitor.

Power Ground

Regulator Output pin. Must be closely decoupled to PGND with a 4.7μF or greater ceramic

capacitor.

ADJ

Adjustable Pin. Connect to a resistive voltage divider to set the output voltage of the device.

Signal ground. Connect with a separate trace to the ground of the output being regulated.

Connect to PGND.
