Pin Name
Description
1 IN Input pin. A small capacitor is needed from this pin to ground to assure stability

OUT
Regulated output voltage pin. A small 10 mF ceramic capacitor is needed from this pin to ground to as-
sure stability
3, EXP
GND
Power supply ground
2 EN Enable pin. Driving this pin high turns on the regulator. Driving EN pin low puts the regulator into shut-
down mode
5
SNS
Sense pin. Connect this pin to regulated output voltage or resistor divider (adjustable version)
4 PG Power Good, open collector. Use 10 kΩ to 100 kΩ pullup resistor connected to output or input voltage

Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product
performance may not be indicated by the Electrical Characteristics if operated under different conditions.
3. Guaranteed by design and characterization.
4. Performance guaranteed over the indicated operating temperature range by design and/or characterization production tested at TJ = TA
= 25_C. Low duty cycle pulse techniques are used during testing to maintain the junction temperature as close to ambient as possible.
5. Respect SOA.
