Name and Function
1
SHDN
Shutdown control (active low): If connected to GND the IC is in shutdown.
Connect to V
CC
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 1
μ
F ceramic capacitance and large
value electrolytic capacitor in parallel. The 1
μ
F capacitor must be as close as
possible to the GND and V
