CC
Shutdown control (active low): If connected to GND the IC is in shutdown. Connect to V
for normal operation (ON MODE).
Reference output voltage: (1.25V): Bypass to GND with 47nF capacitor.
Soft start: a capacitor between SS and GND provides soft-start and short-circuit
protections.
Compensation capacitor input: externally compensates the outer (voltage) feedback loop.
Connect to OUT with 330pF capacitor
Output voltage sense input: provides regulation of feedback sensing. Connect to 3.3V
output.
Ground
Switch output. Drain of internal P-channel power MOSFET
Supply voltage input. Bypass to GND with 1μF ceramic capacitance and large value
electrolytic capacitor in parallel. The 1μF capacitor must be as close as possible to the
GND and V
CC
pins.
