Pin Function
LOWQ Mode. Active Low Input. Logic High = Full Power Mode; Logic Low =
LOWQ Mode; Do not leave floating.
Internal circuit bias supply. It must be de-coupled to signal ground with a 0.1μF
capacitor and should not be loaded.
Signal ground.
Power ground.
Switch (Output): Internal power MOSFET output switches.
Supply Input – DC/DC. Must be tied to PIN7 externally.
Supply Input – LDO2. Must be tied to PIN6 externally.
Output of regulator 2
Feedback. Input to the error amplifier for DC to DC converter.

LDO Output: Connect to V
OUT
of the DC/DC for LOWQ mode operation.
Output of regulator 1
Power-On Reset Output: Open-drain output. Active low indicates an output
undervoltage condition on either one of the three regulated outputs.
Delay Set Input: Connect external capacitor to GND to set the internal delay for the
POR output. When left open, there is minimum delay. This pin cannot be grounded.
Reference Bypass: Connect external 0.1μF to GND to reduce output noise. May be
left open.
Enable Input (DC/DC and LDO1). Active High Input. Logic High = On; Logic Low =
Off; Do not leave floating.
Enable Input (LDO 2). Active High Input. Logic High = On; Logic Low = Off; Do not
leave floating
