______________________________________________________________Pin Description
Ground
GND
5
Positive Power-Supply Input. Must be tied together. Place a 0.1F input bypass capacitor as close to
the V+ and GND pins as possible.
V+
6, 7
Drain of the Internal P-Channel Power MOSFET. LX has a peak current limit of 0.75A.
LX
8
1.5V Reference Output that can source 100A for external loads. Bypass to ground with a 0.1F capacitor.
REF
4
Active-High Shutdown Input. With SHDN high, the part is in shutdown mode and the supply current is less
than 5A. Connect to ground for normal operation.
SHDN
3
PIN
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.
FB
2
Sense Input for Fixed-Output Operation (VFB = VREF). OUT must be connected to VOUT.
