Description
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.
Power Input Pin. Must be closely decoupled to PGND pin with a 4.7μF or greater
ceramic capacitor.
Power Good open Drain Output. When used it should be pulled up to VIN with a
resistor. Typical resistor value 100k.
Regulator Output pin. Must be closely decoupled to PGND pin with a 4.7μF or
greater ceramic capacitor.
Adjustable Pin.
Connect to a resistive voltage divider to set the output voltage of the device.
Power Ground
Connect to PGND.
Signal ground. Connect with a separate trace to the ground of the output being
regulated.
