Pin Function
Supply Input. (V
Enable Input (regulator 1). Active High Input. Logic High = On; Logic Low = Off;
Do not leave floating
Enable Input (regulator 2). Active High Input. Logic High = On; Logic Low = Off;
Do not leave floating
LowQ™ Mode. Active Low Input. Logic High = Full Power Mode; Logic Low = Light
Load Mode; Do not leave floating.
Reference Bypass: Connect external 0.01µF to GND to reduce output noise. May
be left open.
Ground.
Delay Set Input: Connect external capacitor to GND to set the internal delay for the
POR output. When left open, there is no delay. This pin cannot be grounded. Delay
= 1µs/1pF
Power-On Reset Output: Open-drain output. Active low indicates an output
undervoltage condition on either regulator 1 or regulator 2 when device is enabled.
Output of regulator 2
Output of regulator 1
Ground. Internally connected to the Exposed Pad.
