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 regula-
tor.
Analog ground.
No connect (no internal connection to die).
Feedback (Input): Output voltage sense node. Connect feedback resistor
network to this pin. V_OUT = 1.24V ^{1+} _RR21^{}
Switch node (Input): Internal power Bipolar collector.
Power ground.
Ground (Return): Exposed backside pad.
