VOUT

Regulated Output Voltage. Bypass VOUT to GND with a 2.2 µF or greater

capacitor.

SENSE/ADJ

Sense Input (SENSE). Connect to load. An external resistor divider may

also set the output voltage higher than the fixed output voltage (ADJ).

EN

The enable pin controls the operation of the LDO. Drive EN high to turn

on the regulator. Drive EN low to turn off the regulator. For automatic

startup, connect EN to VIN.

SS

Soft Start. An external capacitor connected to this pin determines the

soft-start time. Leave this pin open for a typical 380 μs start-up time. Do

not ground this pin.

VIN

Regulator Input Supply. Bypass VIN to GND with a 2.2 µF or greater

capacitor.

EP

Exposed Pad. The exposed pad on the bottom of the package enhances

thermal performance and is electrically connected to GND inside the

package. It is recommended that the exposed pad connect to the

ground plane on the board.
