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.
Active high signal drives open-drain N-channel MOSFET.
Ground: Connect externally to Exposed Pad.
Open-Drain Output: Capable of sinking 150mA.
Error Flag 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.

+ 1V relative to the highest output voltage.
6. Dropout voltage is defined as the input-to-output differential at which the output voltage drops 2% below its nominal value measured at 1Vdifferential.
For outputs below 2.25V, dropout voltage is the input-to-output voltage differential with the minimum input voltage 2.25V. Minimum input operating
