FUNCTION
Sense Input for Fixed-Output Operation (V FB = V REF ). OUT must be connected to V OUT .
Feedback Input. Connect FB to REF to use the internal voltage divider for a preset output. For adjustable-
output operation, use an external voltage divider, as described in the section Setting the Output Voltage.
Active-High Shutdown Input. With SHDN high, the part is in shutdown mode and the supply current is less
than 5μA. Connect to ground for normal operation.
1.5V Reference Output that can source 100μA for external loads. Bypass to ground with a 0.1μF capacitor.
Ground
Positive Power-Supply Input. Must be tied together. Place a 0.1μF input bypass capacitor as close to
the V+ and GND pins as possible.
Drain of the Internal P-Channel Power MOSFET. LX has a peak current limit of 0.75A.
