Pin Function

Output pin (Output): Output voltage. Connect to FB resistor divider. This pin

has an internal 34V output overvoltage clamp. See “Block Diagram” and

“Applications” section for more information.

Supply (Input): 2.5V to 10V input voltage.

Enable (Input): Logic high enables regulator. Logic low shuts down regulator.

Analog ground.

No connect (no internal connection to die).

Feedback (Input): Output voltage sense node. Connect feedback resistor

network to this pin.

VOUT

= 1.24V⎜⎛1 + R1 ⎟⎞ .

⎝ R2 ⎠

Switch node (Input): Internal power Bipolar collector.

Power ground.

Ground (Return): Exposed backside pad.
