Pin Descriptions

Name

Pin Number

Function

SO-8EP

MSOP-8EP

GND

Ground

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

VOUT

3/4

Power Output Pin. Connect at least 10µF capacitor to this pin to improve transient response and

required for stability. When the part is disabled the output is discharged via an internal pull-low

MOSFET.

VIN

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.

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.

PAD

Exposed pad connect this to VIN for good thermal conductivity.
