Pin Description
Pin Number Pin Name Function
1 COMP
Compensation Point. COMP is used to compensate the regulation control
loop. Connect R and C from COMP and GND to compensate the regulation
control loop
2 GND
Ground. The exposed pad is soldered to PCB and connected to GND plant
for good power dissipation
3 EN
Enable Input. EN is an input when the regulator on or off. When left
unconnected, EN pin is pulled to VDD by the internal pull up resistor
4 VDD
Power input V
IN
provides the input power to the regulator. Connecting a
ceramic bypass capacitor between VDD and GND to eliminate input
noise and ripple voltage
5
6
SW
Switch Output. SW is the switching point which supplies voltage and
current to output
7 F_ADJ
Oscillator Resistor Input. Connecting a resistor to ground from this pin sets
the switching frequency
8 FB
Feedback Input. Receives the feedback voltage from a resistive divider
connected across the output. The feedback reference voltage is 0.8V
typically
