Pin Function
Supply Input: (VIN1 and VIN2 are internally tied together.)
Enable Input to Regulator 1: Enables regulator 1 output. Active high input.
High = on, low = off. Do not leave floating.
Enable Input to Regulator 2: Enables regulator 2 output. Active high input.
High = on, low = off. Do not leave floating.
Reference Bypass: Connect external 0.01µF to GND to reduce output noise.
May be left open.
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.
Ground: Connect externally to Exposed Pad.
No Connection.
Power-On Reset Output: Open-drain output. Active low indicates an output
undervoltage condition on regulator 2.
Output of Regulator 2: 300mA output current.
Output of Regulator 1: 150mA output current.
Ground: Internally connected to the Exposed Pad. Connect externally to
pin 6 of the IC.
