NAME
FUNCTION
1
POK
Open-Drain Power-OK Output. POK is high impedance when output voltage is in regulation. POK sinks current
when V
FB
falls below 1.1V. Connect a 10k
to 1M
pull-up resistor from POK to V
OUT
for a logic signal.
Ground POK or leave unconnected if not used. POK is high impedance in shutdown.
2
SHDN
Shutdown Input. Drive high for normal operation; drive low for shutdown mode. OUT is high impedance in
shutdown.
PIN
3, 4
IN
Input Supply. Connect both pins together and bypass to GND with a ceramic capacitor (see
Capacitor
Selection
section).
5
GND
Ground. Connect GND to PGND with a short trace.
9
OUT
Power Output. Bypass to GND with an output filter capacitor.
8
CXP
Positive Terminal of the Charge-Pump Transfer Capacitor
7
CXN
Negative Terminal of the Charge-Pump Transfer Capacitor
6
PGND
Power Ground. Charge-pump current flows through this pin.
10
FB
Dual-Mode Feedback. Connect FB to GND for 3.3V output. Connect to an external resistor divider to adjust
the output voltage from 2.5V to 5.5V.
