Pin Assignment

Pin Description

5-Lead SOT-23

6-Lead 3x3mm MLP

Pin No.

Pin Name

Pin Description

Supply voltage input.

2

GND

Ground.

3EN

Enable Input. Logic high enables the chip and logic low disables the chip and reduces

supply current to <1

µA. Do not float this pin.

4

FB

Feedback Input. In case of fixed voltage options, connect this pin directly to the output.

For an adjustable voltage option, connect this pin to the resistor divider.

Inductor pin. This pin is connected to the internal MOSFET switches.

Pin No.
