Enable Control for Output 2. Drive logic high to enable output 2, or logic low to disable the
output. Connect to V
O utp ut 3 n- M O S FE T D r i ve. D r i ves the g ate of an exter nal n- channel M O S FE T to r eg ul ate outp ut 3.
DRV3 is internally pulled to ground when EN3 is logic low. Connect an external series RC circuit
for compensation. See the Stability Compensation section.
Feedback Input for Output 2. Connect to the center of a resistor-divider between output 2 and
GND to set the output voltage of output 2. The feedback regulation voltage is 0.500V. See the
Output Voltage Setting section.
Feedback Input for Output 3. Connect to the center of a resistor-divider between output 3 and
GND to set the output voltage of output 3. The feedback regulation voltage is 0.500V. See the
Output Voltage Setting section.

Enable Control for Output 3. Drive logic high to enable output 3, or logic low to disable the
output. Connect to V
+5V or +12V Supply Input. Connect to external +5V or +12V supply rail. Bypass with a 0.1µF
ceramic or larger capacitor.
Output 3 Power-Good Signal. Open-drain output pulls low when output 3 is 12% below the
nominal regulated voltage.
No Internal Connection
Output 2 Power-Good Signal. Open-drain output pulls low when output 2 is 12% below the
nominal regulated voltage.
