Function

SO-8EP

MSOP-8EP

U-DFN3030-10

Power Good.Output open drain to indicate the status of VOUT via monitoring the FB pin.

This pin is pulled low when the voltage is outside the limits, during thermal shutdown and

if either VCNTL or VIN go below their thresholds.

Enable Pin. Driving this pin low will disable the part. When left floating an internal current

source will pull this pin high and enable it.

VIN

7,8,9

Power Input Pin for current supply. Connect a decoupling capacitor (≥10µF) as close as

possible to the pin for noise filtering

VCNTL

BIAS supply for the controller, recommended 5V. Connect a decoupling capacitor (≥1µF)

as close as possible to the pin for noise filtering.

No Connection

VOUT

1,2,3

Power output pin

Feedback to set the output voltage via an external resistor divider between VOUT and GND

GND

Ground

PAD

Exposed pad connected to GND for good thermal conductivity
