Description

1

1

EN

Enable Input. Drive EN high to turn on the regulator; drive it low to turn off the

regulator. For automatic startup, connect EN to IN.

2

IN

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

3

3

3

OUT

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

capacitor.

4

SS

Soft Start. A capacitor connected to this pin determines the soft-start time.

4

ADJ

Adjust. A resistor divider from OUT to ADJ sets the output voltage.

4

TRK

Track. The output will follow the voltage placed on the TRK pin. (See the

Theory of Operation section for a more detailed description.)
