Pin Description
Pin Number    Pin Name   Pin Function
1
AGND    Analog (signal) Ground.
2
LDO     LDO Output (Output): Connect to a 2.2礔 output capacitor.
3
BIAS     Internal circuit bias supply. Must be de-coupled to signal ground with a 0.1礔
capacitor and should not be loaded.
4
AVIN     Analog Supply Voltage (Input): Supply voltage for the analog control circuitry
and LDO input power. Requires bypass capacitor to GND. It must be tied to
VIN.
5
FB     Feedback. Input to the error amplifier. For the Adjustable option, connect to the
external resistor divider network to set the output voltage. For fixed output
voltage options, connect to V
OUT
 and an internal resistor network sets the output
voltage.
6
EN     Enable (Input). Logic low will shut down the switching regulator reducing the
quiescent current to less than 5礎.
7
ENLDO
Enable LDO (Input): Logic low will shut down the LDO, reducing the quiescent
current to less than 5礎.
8
VIN     Supply Voltage (Input): Supply voltage for the internal switches and drivers.
9
SW     Switch (Output): Internal power MOSFET output switches.
10
PGND    Power Ground.
