Feedback input. When V
use an external voltage divider, as described in the Adjustable Output section.
Active-high shutdown input. With SHDN high, the part is in shutdown mode and the supply current is less
than 5µA. Connect to GND for normal operation.
1.5V reference output that can source 100µA. Bypass to ground with 0.1µF.
Positive power-supply input
Noninverting input to the current-sense comparator. Typical trip level is 210mV (relative to V+).
The gate-drive output for an external P-channel power MOSFET. EXT swings from OUT to V+.
