CS
Power-Supply and Voltage-Sense Input. Always connect OUT to circuit output.
Feedback Input for Adjustable-Output Operation. Connect to ground for fixed-output operation.
Use a resistor divider network to adjust the output voltage. See Setting the Output Voltagesection.
Active-High TTL/CMOS Logic-Level Shutdown Input. In shutdown mode, V
OUT
is a diode drop
below the input voltage (due to the DC path from the input voltage to the output). Connect to
ground for normal operation.
1.5V Reference Output that can source 100

F.
The reference is disabled in shutdown.
Positive Input to the Current-Sense Amplifier. Connect the current-sense resistor between CS
and AGND.
